Part of Sciatica

How long does sciatica last? What the recovery studies found

A few weeks to a few months, for most people. That is what the NHS says, and the trials back it up: in a Dutch study of 183 people with sciatica, 87 percent said they had improved by 12 weeks. Recovery is slower for some. In a UK study of 609 adults who saw their family doctor with back-related leg pain, just over half had improved by a clear margin a year later, and those who expected a long problem were less likely to have improved. Leg pain that has lasted months often still eases, with or without an operation.

Warning signs, and when to get help

How long does sciatica last for most people?

The NHS gives a range of a few weeks to a few months. That is a fair summary. The studies that followed people over time show where in that range most of them land, and their numbers differ mainly because each one started with a different group of people.

In a Dutch trial published in 1999, 183 people with sciatica bad enough that bed rest was being considered were split between two weeks in bed and carrying on as normal. Bed rest made no difference. By 12 weeks, 87 percent in both groups said they were better (Vroomen and colleagues, 1999).

A second Dutch trial picked people later in the course: 283 adults whose severe sciatica had already lasted 6 to 12 weeks. Half were offered early surgery. The other half carried on with non-surgical care and could have an operation later if they needed one. In that non-surgical group, the median time until symptoms had gone or nearly gone was about 12 weeks from joining the trial, against about 4 weeks after early surgery. By one year, about 95 percent of both groups felt they had recovered (Peul and colleagues, 2007).

Family doctor patients are a broader mix. The UK ATLAS study followed 609 adults with leg pain linked to their back, including people whose leg pain was referred from the back rather than coming from a pinched nerve root. Average leg pain fell from 5.2 out of 10 to 2.8 at 4 months and 2.4 at a year, and 55 percent had improved their disability score by at least 30 percent at the one year mark (Konstantinou and colleagues, 2018).

If your pain stays in your back and does not run down the leg, a different timeline applies, and how long does back pain last covers it.

What does sciatica recovery look like, stage by stage?

The first two weeks are usually the hardest. In practice, sleep, sitting and the first steps in the morning are what people find worst. The aim at this point is to keep moving in short spells and find positions that quiet the leg. Sleeping with sciatica and sciatica pain when sitting cover the two positions people struggle with most.

By about 12 weeks, most people in the trials above had improved. Progress is rarely a straight line, though. A bad day after a long car trip or a busy weekend does not mean you have gone backward, and driving with sciatica has tips for the journeys you cannot avoid.

Pins and needles and numbness can take longer to fade than the pain. Physios see this often, but it is practice experience rather than a figure from a trial. Strength needs work of its own once the pain allows it, which is what stage 3 of the sciatica program is for.

Why is my sciatica not going away?

Two findings from the ATLAS study help here. People whose leg pain had already gone on for longer before their first appointment were less likely to improve over the following year. So were people who strongly believed their problem would last a long time (Konstantinou and colleagues, 2018). These are links, not proof of cause. Even so, tell your physio honestly how long you think this will take, since your answer changes what kind of support will help.

Sciatica past about 3 months falls under the usual definition of chronic pain (Treede and colleagues, 2019). Plenty of people still recover from this point. In a Canadian trial of people with sciatica from a slipped disc that had lasted 4 to 12 months, the non-surgical group started with average leg pain of 8.0 out of 10 and reported 5.2 six months later. The surgery group did better, at 2.8 (Bailey and colleagues, 2020).

When progress stalls, look at what might be keeping the nerve irritated. Long stretches of sitting, strong hamstring stretches and a program that pushes symptoms down the leg are the usual suspects, and exercises to avoid with sciatica goes through them. NICE NG59 lists further options, including an epidural injection for acute and severe sciatica, and an operation to take pressure off the nerve when non-surgical care has not helped and a scan matches the symptoms. The lumbar disc herniation page covers the commonest cause in more depth.

What helps sciatica settle?

Rest does not speed it up. The 1999 bed rest trial is the clearest test: two weeks lying down gave the same result at 12 weeks as getting on with the day. The NHS advice to keep up your normal routine and avoid long spells sitting or lying down follows from findings like these.

What you can control is how much the leg gets stirred up on a given day. Walk in short spells, change position often, and adjust your exercises to how the leg responds. That keeps you active while the nerve calms down. Gentle nerve glides are one option your physio may add once the leg is a little calmer.

When should you get sciatica checked?

See a GP or a physio if the leg pain has not started to improve after a few weeks of home treatment, is getting worse, or is stopping you from working or doing your usual activities. Those timings come from the NHS. You do not need to wait for the 3 month mark.

How fast you act depends on what the symptoms are, more than on how long you have had them. Changed feeling around your genitals or bottom, or new trouble with your bladder or bowels, means calling emergency services or going to an emergency department straight away. If your foot has started to drag or slap down as you walk, get medical advice the same day, or go to an emergency department if the weakness is getting worse by the hour. The warning list below gives every sign with its timing, and when sciatica needs urgent care explains each one.

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. 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, or new trouble getting an erection or ejaculating. Call emergency services or go to an emergency department straight away. 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.
  • 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 comes with pain spreading down an arm or leg, weakness, numbness or pins and needles in your arms or legs, trouble walking, or trouble controlling your bladder or bowels. 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. 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. This can be an infection pressing on the nerves in the spine (spinal epidural abscess), which needs emergency treatment.

Common questions

How long does sciatica take to heal?

Most people find the leg pain settles over a few weeks to a few months. In a UK study that followed 609 adults after they saw their family doctor with back-related leg pain, average leg pain dropped from 5.2 out of 10 at the start to 2.8 at 4 months and 2.4 at one year (Konstantinou and colleagues, 2018). So most of the change came in the first few months, and the rest was slower. In practice, pins and needles and numbness can take longer to fade than the pain does, though the studies above did not report this.

Why is my sciatica not going away?

Slow recovery is common and is not usually a sign that something has been missed. In the UK ATLAS study, two things went with a lower chance of improving at one year: leg pain that had already lasted a long time before the first appointment, and a strong belief that the problem would last a long time (Konstantinou and colleagues, 2018). If your leg has not started to improve after a few weeks, is getting worse, or stops you doing your usual activities, the NHS advises seeing a GP, and a physio can review the plan with you.

When does sciatica become chronic?

Pain that lasts or keeps coming back for more than 3 months is called chronic in the international classification of chronic pain (Treede and colleagues, 2019), and that classification covers nerve pain such as sciatica. Chronic does not mean permanent. In a Canadian trial of people whose sciatica had already lasted 4 to 12 months, the group given non-surgical care had average leg pain of 8.0 out of 10 at the start and 5.2 six months later (Bailey and colleagues, 2020).

Will sciatica go away without surgery?

For most people, yes. In a Dutch trial of 283 people whose severe sciatica had lasted 6 to 12 weeks, surgery brought relief faster, but at one year about 95 percent of both groups felt recovered (Peul and colleagues, 2007). About 4 in 10 of the non-surgical group did go on to have an operation within that year. For leg pain lasting 4 to 12 months, a Canadian trial found less leg pain at 6 months after surgery than with non-surgical care (Bailey and colleagues, 2020). Whether an operation suits you is a decision to make with a spinal surgeon.
