Part of Lumbar disc herniation
Can a herniated disc heal on its own, and what does healed mean?
Warning signs, and when to get help
Can a herniated disc heal on its own?
Often, yes. The trouble is that the word healed is doing two jobs inside that question. It can mean your leg has stopped hurting, and it can mean the piece of disc pressing against the nerve has got smaller. Those two things are counted by different studies, and either one can move while the other sits still.
The NHS describes a slipped disc as usually getting better slowly, with rest, gentle exercise and painkillers, and says surgery is not usually needed. That page attaches no timeframe to the word slowly, which is the first thing to know before you read any numbers. The guideline group at the North American Spine Society went looking for reliable evidence on what untreated herniations do over time and did not find any, so what it published was consensus opinion, which was that most people improve whatever the treatment and that herniations often shrink (Kreiner and colleagues, 2014).
So the rest of this page separates the two things most pages run together. It is the separation, not the figures, that tends to settle people. All of it rests on one assumption: that somebody has examined you and told you this is a disc. If nobody has, the figures below are not yet about you, because leg pain has several other causes and these percentages come from people whose herniation had been seen on a scan, so an assessment comes first, not a wait. If you want the exercise side of this, the lumbar disc herniation program has the staged version, and sciatica covers the leg pain itself.
Two clocks: the scan and the symptoms
Two clocks are running here. The evidence describes them separately, so this page does too.
The first is the scan clock. It ticks when the herniation shrinks, and it is read off repeat MRI scans in people who were treated without an operation. The second is the symptom clock. That one ticks when the leg pain fades, when the pins and needles go, when you can drive to work and sit through a meeting. Trials measure it with pain scores and disability questionnaires, never with pictures.
The figures below come from two separate bodies of research, measuring two separate things in two separate groups of people. That part rarely gets said out loud. We are not citing a study that followed both clocks in the same patients and reported how often the two moved together, so a percentage about scans is a statement about scans and nothing more. Feeling better does not require the picture to change, which is the whole lesson of what scans show in people with no pain at all.
What that means on a Tuesday afternoon is simple enough. Progress is judged by how far down your leg the symptoms reach and by what you managed this week, not by a second scan. How to read your leg while you are doing the exercises is set out on the lumbar disc herniation program.
What happens to the herniation on a repeat scan?
Most of them get smaller. The types with the frightening names on your report are the ones most likely to do it.
Two things before the numbers, because of the way they get read. Each one is a group rate taken from people who happened to be scanned twice, so it tells you what became of a hundred of them and nothing about what your own nerve is doing this week. And if you have no scan report in front of you, none of the four lines below is yours to claim: somebody saying the word disc out loud is not the same as a radiologist naming the finding, and the four findings are not interchangeable.
A systematic review gathered 31 studies of people managed without surgery who had at least two scans, and calculated the probability of regression from the nine studies that used the standard reporting words (Chiu and colleagues, 2015). Rates of shrinking, by what the report calls the finding:
- Sequestration, where a fragment has broken away from the disc completely: 96%
- Extrusion, where the pushed-out part is wider than its base: 70%
- Protrusion, where the pushed-out part is narrower than its base: 41%
- Bulge, where the disc edge spreads out around more than a quarter of its circumference rather than pushing out in one spot: 13%
The same review found the herniation had vanished altogether in 43% of sequestrations and 15% of extrusions. A later meta-analysis pooled 11 cohort studies and put the overall rate of resorption during non-surgical treatment at about two thirds, while noting that the data sources were few and that no randomized trials were eligible for it (Zhong and colleagues, 2017). If the words on your own report mean nothing to you, what the terms on a disc scan report mean is set out on the main page, and they follow the nomenclature the North American spine and radiology societies agreed (Fardon and colleagues, 2014).
Non-surgical, in those studies, did not mean untreated. Everyone counted in them was having treatment, just not an operation, so healing on its own means without surgery and not without help. Nobody in them had had the herniation taken out either, so none of these figures describes a disc that has already been operated on.
The review set other people aside as well, and that list is one to hold next to your own report. A study only counted if it had excluded anyone with narrowing of the spinal canal (spinal stenosis), a vertebra slipped forward on the one below (spondylolisthesis), a spinal infection, a tumor, or earlier lumbar surgery (Chiu and colleagues, 2015). So if your report names one of those alongside the herniation, these percentages are not a description of your scan. Spinal stenosis and spondylolisthesis each have a page of their own, and either can be what is driving leg pain while the herniation takes the blame.
One more group is not in these numbers at all. Neither review reports a figure for a child or a teenager, and the NICE guidance this page relies on for the imaging advice further down is written for people over 16. A disc herniation in someone still growing is uncommon and it does not behave the same way: a broken piece of the bony growth rim at the back of the vertebra is a characteristic finding on the scan, and that is bone, not disc material, while non-surgical treatment is still what gets tried first but works less well than it does in adults (Zhang and colleagues, 2025). So back and leg pain in a child or a teenager goes to a doctor who can examine them, and the list above is not the thing to go on.
Those numbers come with a caution on each side. People only appear in these studies because somebody scanned them twice, and a second scan tends to be ordered for a reason, so this is not a random sample of everyone with a disc herniation. On the other hand, nothing in the list above tells you what your own nerve is doing this week. A sequestration with a 96% chance of shrinking can still be the one that leaves your foot weaker by Friday, and that is a reason to be seen, not a reason to wait for the statistics to come good.
If you are matching your own report to that list, two things follow. These words are a radiologist's description of a picture, and the standard behind them was written in 2001 and rewritten in 2014 to get clinicians and radiologists using them consistently (Fardon and colleagues, 2014), which tells you plainly enough that they had not always been used the same way. And the findings at the top of the list, the ones most likely to shrink, are the ones with the most material pushed out of the disc, which is also the most material available to press on nerves. That is what the emergency signs at the end of this page are about. A high percentage for your type is not a safety margin, and it is not a substitute for somebody examining your leg.
Do herniated discs heal completely, or just enough?
Usually just enough. For most people that turns out to be plenty.
Go back to the disappearance figures in that review. Complete resolution reached 43% of sequestrations and 15% of extrusions, so even in the two types most likely to shrink, the majority still had something left to see (Chiu and colleagues, 2015). A report that still shows a herniation later on is the ordinary outcome, not the mark of a recovery that failed.
What makes that bearable is what the scans look like in people who have no symptoms. In a review of imaging studies in pain-free people, disc bulges appeared in 30% of 20-year-olds and 84% of 80-year-olds, while protrusions ran from 29% at 20 to 43% at 80 (Brinjikji and colleagues, 2015). Plenty of people are getting on with their lives carrying a finding much like yours, and they will never know, because nobody is going to scan them. A picture cannot tell you whether you are better, which cuts both ways: it also cannot reassure you that you are, so the examination earns its place instead of losing it. If your report came back loaded with words like degeneration and desiccation, degenerative disc disease deals with that label specifically.
A reasonable working definition of healed, then, is the one your own life gives you. Sleeping through the night, sitting out a long drive, lifting your own shopping, going back to the thing you stopped doing. That is the version your physio can measure with you, and it is the version the trials below actually counted.
One thing does not belong on that list. If the leg pain eases but numbness or weakness in the leg gets worse, that is not healing. Stop the exercises and get medical advice the same day.
How long does a herniated disc take to heal?
For the symptoms, weeks to months for most people, with a long tail that nobody should hide from you.
The clearest trial recruited 283 adults in the Netherlands whose severe sciatica from a disc herniation had already lasted 6 to 12 weeks, and offered half of them early surgery (Peul and colleagues, 2007). By one year, roughly 95% of both groups were estimated to feel recovered, and 39% of the non-surgical group had an operation along the way. The same trial reported again at two years, and this is the half that usually gets left out: 62 of the 142 people in the non-surgical arm, which is 44%, had eventually had surgery, seven of them during the second year; there was no significant overall difference in disability between the two groups across the two years; and 20% of everyone in the trial still reported an unsatisfactory outcome at that point (Peul and colleagues, 2008). Each of those numbers belongs to a different follow-up. The 39% is a one-year figure and the 44% is a two-year figure for the same group of people, and they are not two different findings.
Who was in that trial matters as much as the percentages. Everyone had severe leg pain that had already run for between six and twelve weeks, so these figures describe a group that was struggling by the time it was counted, and they are not a timetable for someone three days into a sore back. For the wider picture of how leg pain settles, including the people who see a family doctor and not a surgeon, how long does sciatica last has the cohort studies.
For the scan clock there is no honest timeframe here. The reviews above counted how often a herniation shrank, not how quickly, so any page offering you six weeks or six to twelve months for the disc itself is quoting something other than this evidence.
Why a repeat scan is usually not the answer
Because a second picture rarely changes what anyone does. It can also leave you feeling worse than you did before you read it.
Outside specialist care, NICE advises against routine imaging for low back pain, with or without sciatica, and inside specialist care it asks that a scan be considered only where the result is likely to change the treatment. Both halves matter here. A scan ordered to answer the question "has it healed?" has no treatment hanging off its answer, and given how often these findings sit in pain-free people, it will quite often hand you a worrying line of text with no action attached.
There is a difference, though, between not needing a repeat scan and not needing to be seen. Imaging is arranged when the answer would change the plan, which usually means an operation or an injection is on the table, and it is arranged urgently when a doctor suspects cauda equina syndrome. If your symptoms are not settling, or an operation has come into the conversation, surgery or physio for a herniated disc sets out how that decision is made. If you are not sure whether what you are feeling has crossed a line, when sciatica needs urgent care goes through each sign in turn.
One group of readers should take none of the paragraph above. If you have already had an operation on this disc, this page is not describing you. The shrinking figures come from people whose herniation was still in place, and the advice against a repeat scan is written for someone who has not been operated on. Leg pain that comes back, or never left, after a discectomy raises a different question: whether the disc has herniated again, whether scar tissue around the nerve is part of it, or whether something else is going on. That is an examination and an imaging decision for the team that operated on you, and there the answer can be that a scan is exactly what you need. So take new or returning leg pain, numbness or weakness to them rather than waiting it out, and surgery or physio for a herniated disc covers how that conversation is had.
Does a bulging disc heal the same way?
Not quite. The reason sounds like bad news until you follow it through.
A bulging disc was the finding least likely to shrink on a repeat scan, at 13% (Chiu and colleagues, 2015). On the reporting standard it is not a herniation in the first place: the edge of the disc spreads out widely, instead of a local push of material beyond the disc's normal edge (Fardon and colleagues, 2014). It is also the commonest incidental finding in backs that have never hurt, which is where that 30% to 84% age range above comes from.
A bulge, then, is usually not the thing you are waiting on. Whether it has anything to do with your symptoms is a question for an examination, and a reader whose report says bulge is often better served by asking what is irritating the nerve than by asking when the bulge will go. If your pain stays in your back and never travels down the leg, low back pain suits you better than this page or the disc program.
What makes recovery slower, and what does not
One thing here has decent evidence behind it: how long you have had the symptoms before anything is done about them.
An analysis of the SPORT studies, grouped by the treatment people actually received, compared 927 people whose disc herniation symptoms had lasted six months or less with 265 whose symptoms had run longer, and followed them for up to four years (Rihn and colleagues, 2011). The longer-duration group did worse on pain, physical function and disability at every follow-up, and this held whether they were treated with surgery or without it. That is an association in people who chose their own treatment, not proof that waiting caused the difference. It is still the strongest argument on this page for getting assessed and getting moving now rather than keeping a private count of weeks.
The six month figure is the one people misread most. The NASS guideline makes two suggestions about it, and both are written about the same narrow group. Where the symptoms are severe enough to warrant surgery, it suggests that discectomy relieves them more effectively than medical or interventional care, and that the operation is better done before the symptoms have run six months; where the symptoms are less severe, it says surgery and medical or interventional care both appear to work, in the short term and the long (Kreiner and colleagues, 2014). So the six months belongs to people who already need an operation. It is not a deadline, and reaching six months is not in itself evidence that you need one.
A long history does not shut a door either: in the same SPORT analysis, the extra benefit surgery gave over non-surgical care did not depend on how long the symptoms had lasted (Rihn and colleagues, 2011). Nor is it the clock for everything surgical: the emergency signs at the end of this page are judged in hours, not months, which is why they carry their own instructions.
Two things feel decisive here and are not. The word on your report is one, because the findings with the worst names were the ones most likely to shrink. Whether the picture has changed yet is the other, and the only way to know would be a scan nobody has a reason to order.
What helps meanwhile is less interesting than people hope. The NHS advice is that you may need to rest at first if the pain is very bad, but that you recover faster by starting gentle exercise as soon as you can, and that the type matters less than whether it causes pain or makes your back pain worse. Short rests to ease a bad spell are fine, then get up and move again.
The painkiller half of that advice comes with a condition the NHS prints on the same page, and it is easy to skim past: anti-inflammatory painkillers are not suitable for everyone, so speak to a pharmacist if you are not sure you can take them. Pregnancy is the clearest case of that. The NHS asks you to check with your pharmacist, midwife or doctor before taking any medicine in pregnancy, painkillers included, and that covers the ones you buy for yourself as much as the ones you are prescribed. It also says to avoid ibuprofen in pregnancy unless a doctor or pharmacist has told you otherwise. Back and pelvic pain in pregnancy also has causes that belong to the pregnancy rather than to a disc, so your midwife or maternity team needs to hear about it as well as your physio, and pregnancy back and pelvic pain is the page written for that.
On a disc, read the leg as well as the back. If pain, numbness or tingling spreads further down your leg during or after an exercise, stop that exercise and leave it out for now. If the leg symptoms ease or pull back toward your buttock, physios usually count that as a good response, even if your back aches a little more for a while. Walking is the easiest place to begin, and brisk walking is where the program builds to as the leg quiets down. Lists of factors that supposedly predict whose herniation will shrink are easy to find, and we are not giving you one, because we have read nothing solid enough to turn into a forecast for one person.
Sitting and driving are the two positions a disc usually makes hardest, and they are also the two most people cannot get out of. How to sit and drive with a herniated disc covers what to change about both, including the signs that mean stopping the car.
When to get it looked at again
Good news about healing is not a reason to stop watching. A few things need acting on today, not at your next appointment.
The NHS slipped disc page says to see a GP if painkillers are not helping or the pain is not getting better after a few weeks. It puts four more things in that same box, and they do not all belong in one queue. A high temperature, or feeling hot, cold, shivery or generally unwell, is a same-day call, which is where the NHS back pain page routes it, and so is weight you have lost without trying. Pain that is worse at night or does not ease at all with rest is seen within a few days, or the same day if you also feel unwell, have lost weight without trying, or have had cancer, now or in the past. A lump or swelling in your back, or a back that has changed shape, gets an appointment with your doctor.
A physiotherapist, or a physical therapist in the United States, can also review what you are doing and change it. Being seen is an assessment, which is not the same thing as another scan, and the distinction matters if you have been told you do not need imaging. If the pain has gone but your leg or foot is still weak or numb, book an appointment instead of waiting, even when it has stopped getting worse.
Getting that appointment may not need a doctor first, which is the part most people do not know. In much of the United Kingdom you can refer yourself to an NHS community musculoskeletal service for physiotherapy without going through a GP, and the NHS says so on its own slipped disc page: NHS physio self-referral sets out how it works in each nation. In the United States the American Physical Therapy Association counts every state as allowing a physical therapist to assess and treat you without a physician's referral as of 1 July 2025, although a number of states attach conditions and your insurer may still want a referral, which direct access to physical therapy goes through. Anywhere else, ask the clinic what it needs. Booking that is the thing to do this week, whatever the percentages above are doing.
If you have had an operation or an injection on your spine, one more thing belongs in this section. A spinal infection does not always cause a fever, and a normal temperature is not a reason to be reassured. It is more likely if you have recently had spine surgery or an injection into your spine, inject drugs, or take medicine that weakens your immune system (Finucane and colleagues, 2020). If you have had spine surgery or a spinal injection in the last three months, contact your surgical team the same day about a fever, a wound that is red, hot, swollen or leaking, or back or leg pain that is new or much worse, even without a fever. Redness can be harder to see on brown or black skin.
Feeling better is also not the same as being ready for everything you did before. The stages on the lumbar disc herniation program are how that part gets rebuilt, and finishing it beats stopping at the point where the pain goes.
Two patterns deserve more urgency than the rest. If the leg pain eases but numbness or weakness in the leg gets worse, stop the exercises and get medical advice the same day. A leg or foot that is getting weaker, for example your foot drags, catches on the ground or slaps down when you walk (foot drop). Get medical advice the same day. If the weakness is getting worse by the hour, go to an emergency department.
And one set does not wait at all. Numbness around your genitals or bottom, new trouble with your bladder or bowels, pain, tingling, numbness or weakness in both legs, or loss of feeling in one leg means calling emergency services or going to an emergency department straight away, and not driving yourself there. Nothing on this page about shrinking herniations applies to those signs: they are about pressure on nerves right now, and the figures above have nothing to say about them. The warning list below gives every sign with the timing that goes with it.

Warning signs
Get emergency help now
- Emergency: numbness, tingling or altered feeling around or under your genitals, between your inner thighs, or around your bottom (anus), for example it feels different when you wipe after using the toilet. Call emergency services or go to an emergency department straight away, and do not drive yourself. This can be a sign of pressure on the bundle of nerves at the base of the spine (cauda equina syndrome), which needs emergency treatment.
- Emergency: you find it hard to start peeing, cannot pee, cannot feel yourself peeing or cannot control when you pee, or you do not notice when you need to poo or cannot control when you poo, and this is not normal for you. The same applies to a new change in how your genitals feel during sex, new trouble getting or keeping an erection, new trouble ejaculating, or new trouble reaching orgasm. Call emergency services or go to an emergency department straight away, and do not drive yourself. These can also be signs of cauda equina syndrome.
- Emergency: sciatica in both legs, or pain, tingling, numbness or weakness in both legs. The same applies if you lose feeling in one leg. Call emergency services or go to an emergency department straight away, and do not drive yourself.
- Emergency: back or leg pain that started after a serious accident, such as a car crash or a fall from a height, or back pain with chest pain. Call emergency services. If the pain started straight after the accident, keep still while you wait.
- Emergency: sudden, severe pain in your lower back or tummy that is not like your usual back pain, if you have been told you have a swelling of the main blood vessel in your tummy (abdominal aortic aneurysm), you are over 60, you smoke or used to smoke, or you have high blood pressure. The same applies if sudden, severe back or tummy pain comes with feeling faint or passing out, pale, sweaty or clammy skin, a racing heartbeat or being short of breath. Call emergency services straight away. This can be a sign of an aneurysm bursting, which needs treatment in hospital at once.
- Emergency: new neck or back pain after a fall, a knock or a jolt, even a minor one such as a trip or a sudden stop in a car, if you have a condition that stiffens the spine, such as ankylosing spondylitis. Call emergency services or go to an emergency department straight away, do not drive yourself, and tell the staff about your spine condition, so they keep your neck and back in their usual position. A stiff spine can break after a small injury, and the break is easy to miss at first. If the pain started straight after the injury, or you also have numbness, tingling or weakness in your arms or legs, keep still and call emergency services.
- Emergency: you have had cancer, now or in the past, and your back or neck pain feels like a tight band around your body, or you have new or worsening pain spreading down an arm or leg, weakness, numbness, pins and needles or a loss of feeling in your arms or legs, trouble walking, or trouble controlling your bladder or bowels. Those symptoms count on their own, with or without back or neck pain. Call your cancer team's emergency number straight away, or go to an emergency department if you do not have one or cannot get through, and do not drive yourself. This can be cancer pressing on the spinal cord (metastatic spinal cord compression), which needs treatment straight away.
- Emergency: back pain with a fever, or you feel hot, shivery or very unwell, and you also have new weakness, numbness or tingling in one or both legs, or new trouble with your bladder or bowels. Call emergency services or go to an emergency department straight away, and do not drive yourself. This can be an infection pressing on the nerves in the spine (spinal epidural abscess), which needs emergency treatment.
Get help today
- Same day: a leg or foot that is getting weaker, for example your foot drags, catches on the ground or slaps down when you walk (foot drop). Get medical advice the same day. If the weakness is getting worse by the hour, go to an emergency department.
- Same day: back or leg pain with a fever, or you feel hot, cold, shivery or generally unwell. Get medical advice the same day, and go to an emergency department if you feel very unwell. If you have a very high or very low temperature, shivering you cannot control, you are breathing very fast or finding it hard to breathe, you are confused or your speech is slurred, your skin, lips or tongue look blue, gray, pale or blotchy (on brown or black skin this can be easier to see on the palms of the hands or soles of the feet), or you have a rash that does not fade when you press it, call emergency services, as this can be sepsis.
- Same day: new back or leg pain and you have had cancer, now or in the past, or you have lost weight without trying. Get medical advice the same day and mention it. If you are being treated for cancer now, contact your cancer team the same day.
- Same day: back pain after a minor fall or strain if you are older, have low bone density (osteoporosis) or have taken steroid tablets for a long time. Get medical advice the same day. Until it has been checked, stop the exercises and keep away from lifting, bending forward and twisting, because those load a bone in the spine that may be broken.
- Same day: severe pain that comes on suddenly or is getting worse quickly. Get medical advice the same day.
- Same day: pain that does not ease at all with rest or changing position, or is worse at night. Get medical advice the same day if you also feel unwell, have lost weight without trying, or have had cancer, now or in the past.
- Same day: a calf or thigh that is newly swollen or getting more swollen, warm, tender, red or darker than usual, has swollen veins that are sore to touch, or has a throbbing or cramping pain that does not fit your injury or condition, or that feels different from normal muscle soreness after exercise. This can be a sign of a blood clot (deep vein thrombosis), especially after surgery, an injury, time in a cast or boot, a long trip or a spell of being much less mobile than usual. Get medical advice the same day. If you are also short of breath or have chest pain, call emergency services.
- Same day: if you have had spine surgery or a spinal injection in the last three months, contact your surgical team the same day about a fever, a wound that is red, hot, swollen or leaking, or back or leg pain that is new or much worse, even without a fever. Redness can be harder to see on brown or black skin.
Book an appointment
- Within a few days: pain that does not ease at all with rest or changing position, or is worse at night. See your doctor within a few days.
- Back or buttock pain that started before the age of 45, has lasted more than three months, is worse after rest and in the morning, and eases when you move. This is not an emergency, but see your doctor in the next week or two and ask whether it could be inflammatory back pain (axial spondyloarthritis).
- Routine: back pain that comes from the top of your back, between your shoulders, rather than your lower back, and has not been checked, or back pain that is worse when you sneeze, cough or poo, or comes with a lump or swelling, or a back that has changed shape. Book an appointment with your doctor, as the NHS advises, and have it checked. If the pain came on suddenly, get medical advice the same day.
Common questions
Can a bulging disc heal?
A bulge behaves differently from a herniation on repeat scans, and the reason is partly that a bulge is a different finding. On the reporting standard a bulge is the disc edge spreading out widely rather than a local push of disc material, so it is not counted as a herniation at all (Fardon and colleagues, 2014). It was also the finding least likely to get smaller in the regression review, at 13% (Chiu and colleagues, 2015). Read that next to how common bulges are in people with no pain whatsoever, which runs from 30% of 20-year-olds to 84% of 80-year-olds (Brinjikji and colleagues, 2015), and a bulge is usually not the thing you are waiting on. Whether it explains your symptoms is a question for an examination rather than for the report. See a physio or doctor if your pain is not improving after a few weeks, and the same day if your leg or foot is getting weaker. Numbness around your genitals or bottom, new trouble with your bladder or bowels, pain, tingling, numbness or weakness in both legs, or loss of feeling in one leg means calling emergency services or going to an emergency department straight away, and not driving yourself there.
Does a herniated disc go back into place?
That is not what the research describes, and the phrase has misled a lot of people. The reviews here measured herniations getting smaller or vanishing on a second scan during non-surgical care (Chiu and colleagues, 2015; Zhong and colleagues, 2017), which is disc material being broken down and absorbed over time rather than sliding back where it came from. Nothing in them tested a method for putting it back, so a clinic, a machine or an exercise promising to reseat your disc is claiming more than this evidence supports. The mechanism is not the part that matters to you, though, because recovery is tracked by what your leg does and what you can get done, not by the position of anything. One pattern in the leg is not progress and is worth acting on: if the pain eases while numbness or weakness gets worse, get medical advice the same day.
Can a slipped disc heal without surgery?
For most people, yes, and that is the NHS position: surgery is not usually needed for a slipped disc, and a specialist referral comes up where other treatments have not improved things, or where weakness or numbness is worsening. One half of that is not a wait, whatever the referral route: if weakness or numbness in your leg is getting worse, get medical advice the same day, and if it is getting worse by the hour, go to an emergency department. The honest qualifier is that a sizeable minority do come to an operation. In the Dutch trial of severe sciatica lasting 6 to 12 weeks, 62 of the 142 people in the non-surgical arm, which is 44%, had surgery within two years, seven of them in the second year (Peul and colleagues, 2008). Needing one is not a failure on your part, and it is a decision made with a spine specialist rather than by a clock.
How long does a herniated disc take to heal?
There is no fixed time, and the NHS page says only that it usually gets better slowly, with no figure attached. The clearest number we can give you is about symptoms rather than the disc: among people whose severe sciatica had already lasted 6 to 12 weeks when they joined a Dutch trial, roughly 95% were estimated to feel recovered at one year, with or without early surgery (Peul and colleagues, 2007). For the picture on the scan there is no timeframe here at all, because the reviews we cite counted how often a herniation shrank, not how soon. See a physio or doctor if your pain is not improving after a few weeks, and the same day if your leg or foot is getting weaker. Numbness around your genitals or bottom, new trouble with your bladder or bowels, pain, tingling, numbness or weakness in both legs, or loss of feeling in one leg means calling emergency services or going to an emergency department straight away, and not driving yourself there.
