How to Sleep With Sciatica: Positions and Pillows

What is the best sleeping position for sciatica?

Nobody has run a trial that compares sleeping positions for sciatica. When researchers looked for any study linking sleep posture to spinal symptoms in 2019, they found four, all relying mostly on people's own reports of how they slept, which is too little to settle anything (Cary and colleagues, 2019). So the honest answer is that you test, and your leg tells you the result.

Lie in a position for a few minutes and notice where the pain, pins and needles or numbness sits. If it stays where it was or retreats toward your buttock, keep the position. If it creeps further toward your foot, change it. Physios read the leg the same way during exercise, and symptoms pulling back toward the spine (centralization) are generally a good sign (May and Aina, 2012). The sciatica program uses the same rule.

The NHS self-care advice for sciatica gives two set-ups to start with: a small, firm cushion between your knees when you lie on your side, or several firm pillows under your knees when you lie on your back. Both keep the knees bent. In physio terms, the sciatic nerve runs behind both the hip and the knee, so bending the hip while the knee stays straight puts it under more pull, and bending the knee eases that. This reasoning comes from how the nerve moves, not from a sleep study.

If your pain is mainly in your back rather than your leg, sleeping positions for back pain is the better guide.

Should you sleep on the side that hurts or the other side?

There is no rule, so try both. A common starting point is the pain-free side, with the sore leg on top and the cushion between your knees thick enough that the top knee sits level with the hip. If the top leg slides forward off the cushion, the pelvis rolls with it and the nerve gets pulled. In practice, that is one of the commonest reasons a leg wakes someone at 3 a.m.

Some people prefer lying on the sore side, and that is fine if the leg stays quiet. Give each side about ten minutes before you judge it.

Keep the knees bent but not hugged to your chest. Curling up tight bends the lower back a long way, and physios see that bring the leg pain on in some people with a disc problem rather than ease it. If that happens, straighten out a little and see whether the leg settles.

Lying on your back and lying on your front

On your back, slide two or three firm pillows, or a rolled duvet, under your knees so they stay bent and the back of your thighs can relax. If the leg starts to tingle after a while, add a pillow rather than taking one away.

From about 28 weeks of pregnancy the NHS advises going to sleep on your side rather than on your back, because it says sleeping on your back after that point can double the risk of stillbirth. So use the side position with a firm cushion between your knees, and leave lying on your back until after the birth. The NHS also says not to worry if you wake up on your back: settle onto your side again and carry on. Leg pain in pregnancy is assessed differently, so ask your midwife or maternity physio for a plan, and see the pregnancy back and pelvic pain page.

Lying on your front is not banned. Some people's leg pain eases when the lower back rests in a gentle arch, and lying face down gives exactly that.

Test it in the daytime with prone lying for a few minutes before you try it at night. If the leg settles, it is a reasonable position to fall asleep in. If it sends symptoms down the leg, or the back aches more the longer you stay, leave it. Ask your physio first if you have been told you have narrowing of the spinal canal (spinal stenosis), if you are pregnant, if you have had back or stomach surgery recently, or if a heart or lung condition makes lying on your front hard.

Why is sciatica worse at night?

Hours in one position, a pillow that has slipped and nothing to take your mind off the pain all add up. That is what physios hear most often, though nobody has studied it as such. Poor sleep is common with nerve root pain: in one Turkish study of 66 people with lumbar radiculopathy who had not improved with non-surgical care, about 70 percent scored as poor sleepers on a standard sleep questionnaire (Kocabicak and colleagues, 2014). Those were people whose pain had not settled with non-surgical care, so the figure may not apply to milder cases.

A leg that complains until you turn over is one thing. Pain that never lets up, whatever position you try, is another. If your leg or back pain does not ease at all when you rest or change position, or is worse at night, see your doctor within a few days. Make it the same day if you also feel unwell, have lost weight without trying, or have had cancer. The warning list below gives the full set of signs.

What can you do when sciatica wakes you at night?

Change one small thing first. Turn over, push the cushion back between your knees, or bend your knees a little more. If the leg has not settled after about ten minutes, get up and walk slowly around the house for a few minutes, then go back to bed. In practice, an hour spent lying still and waiting for the leg to go quiet rarely works.

Heat helps some people before bed. The NHS suggests heat packs for sciatica but advises against hot water bottles, because skin that has gone numb can scald without you noticing. Take any heat away before you fall asleep.

If nights are still poor after a few weeks, mention it to your GP or physio. Sleep is part of how they judge whether the plan is working, and how long does sciatica last sets out what a normal recovery looks like.

Getting in and out of bed with sciatica

Sitting straight up from flat, with the legs out in front, bends the hips while the knees are straight, which pulls on the nerve. Rolling avoids it. The log roll out of bed takes you onto your side with your shoulders and hips moving together, then lets your lower legs drop off the edge as your arms push you up to sitting. Pause on the edge before you stand.

If you have had a hip replacement, get the go-ahead from your surgeon or physio before you try the log roll. The bent knees tip across as you roll, which can take the top leg across the middle of your body, and many surgeons ask you to avoid that for the first months after some operations. After back surgery, use the method your surgical team taught you. If you are pregnant, check with your midwife or physio before you start.

Exercises that can help

The log roll is for every trip in and out of bed. Roll out with it each time you get up and reverse it to lie down, while your back stays sore or for as long as your surgeon or physio advises. Prone lying is a position to test during the day before you try it at night: many programs use 2 to 5 minutes at a time, a few times a day. Your physio will adjust this.

Once the leg is calmer in the daytime, gentle nerve glides may join the program, but they belong in the day, not as a fix at 3 a.m. Long evenings on the sofa often show up as a bad night, and sciatica pain when sitting covers how to break them up. On mattresses, the research is summarized on the lower back pain in the morning page, and you do not need to buy anything before trying the pillow changes above. If you are not sure whether a night symptom is urgent, when sciatica needs urgent care explains each warning sign.

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

Should I sleep on my sciatica side?

Try both and let your leg decide. Many people settle best on the pain-free side, with the sore leg on top and a firm cushion between the knees so it cannot slide forward. Others find lying on the sore side quieter once the pillows are right. Give each side about ten minutes. Whichever leaves the pain, tingling or numbness higher up the leg, or no worse, is the one to sleep on. That is a practical test rather than a researched rule, because no study has compared the two sides.

Where should I put a pillow for sciatica?

On your side, a small firm cushion goes between your knees. On your back, several firm pillows go under your knees so they stay bent. Both set-ups come from NHS self-care advice for sciatica. From about 28 weeks of pregnancy the NHS advises going to sleep on your side rather than on your back, because it says sleeping on your back after that point can double the risk of stillbirth. So use the side position with a firm cushion between your knees, and leave lying on your back until after the birth. The NHS also says not to worry if you wake up on your back: settle onto your side again and carry on.

Why is my sciatica worse when lying down?

Usually because one position has been held for a long time, or the position keeps the nerve on a stretch, for example the top leg dropping forward with the knee fairly straight. Turning over, bending the knees more or getting up for a short walk tends to ease that kind of night pain within minutes. That is practice experience. One pattern needs checking: pain that does not ease at all with rest or changing position, or is worse at night. See your doctor within a few days. 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. If you are being treated for cancer now, contact your cancer team the same day.

Is it better to sit or lie down with sciatica?

Neither for long. The NHS advises against sitting or lying down for long periods with sciatica, even though moving hurts, and suggests carrying on with normal activities as much as you can. Short rests to get through a bad spell are fine. In practice, swapping between sitting, lying, standing and short walks every half hour or so suits an irritated nerve better than staying in any one of them.
