Based on NHS guidance and NHS physiotherapy advice.

The short version: try lying on your side with a pillow between your knees, or on your back with a pillow under your knees. Try not to sleep on your front if you can help it, and avoid sleeping on the floor or in a chair. A heat pack before bed can ease the pain, and moving during the day helps more than lying in bed.

Best sleeping positions for sciatica

1
On your side, pillow between your knees
Lie on your side with a pillow between your knees. A second pillow supporting your top arm can help too.
2
On your back, pillow under your knees
Lie on your back with a small pillow under your knees. If lying on your back makes the pain worse, switch to your side.
3
On your front, only if you have to
Sleeping on your front isn't generally recommended, because it's harder to keep your neck in line. If it's the only way you can sleep, a small pillow under your tummy may be more comfortable.

Pillows and your mattress

Head pillows: too many tip your head forward and too few tip it back. People with back pain usually prefer one.
Mattress: it should be comfortable but supportive. A firm mattress usually suits people with back pain. If you're buying one, lie on it in the shop for at least 20 minutes.
Not the floor or a chair: Wirral Community Health and Care NHS Trust advises against sleeping on either when you have back pain.

Before bed

Hold a heat pack on the painful area. The NHS recommends heat packs for sciatica.
Ask a pharmacist which painkillers are right for you, and when to take them.
Stay active in the day. The NHS advice is not to sit or lie down for long periods, and a few gentle sciatica exercises can help.

If the pain wakes you most nights and hasn't improved after a few weeks, see a GP or physio. It's also worth reading how long sciatica usually lasts.

Sleeping with sciatica: questions

Can I sleep on my side with sciatica?

Yes. Lying on your side with a pillow between your knees is one of the positions NHS hospitals suggest for back pain.

Is sleeping on the floor good for sciatica?

No. Wirral Community Health and Care NHS Trust advises against sleeping on the floor or in a chair when you have back pain. A firm, supportive mattress is a better bet.

What mattress is best for sciatica?

There's no single best one. People with back pain usually prefer a firm mattress and one pillow. If you're buying a new mattress, lie on it in the shop for at least 20 minutes before deciding.

Should I stay in bed if my sciatica is bad?

No. The NHS advice is not to sit or lie down for long periods. Get up and move during the day, even if it hurts, because moving isn't harmful and can help you recover faster.

Go to A&E or call 999 if you:

have sciatica on both sides
have weakness or numbness in both legs that's severe or getting worse
have numbness around or under your genitals, or around your bottom (anus)
find it hard to start peeing, cannot pee or cannot control when you pee, and this is not normal for you
do not notice when you need to poo or cannot control when you poo, and this is not normal for you

These can be signs of cauda equina syndrome.
