Sciatica — the shooting, burning pain that travels from the lower back or buttock down the leg when the sciatic nerve is irritated or compressed — has a way of flaring the moment you lie down. The overnight goal is simple: position your spine and hips so the nerve is decompressed rather than pinched. A few adjustments can turn an impossible night into a manageable one. (This is general information, not medical advice.)
Positions that take pressure off the nerve
- On your side with a pillow between your knees. Keeping the knees and hips aligned stops the top leg from rotating the pelvis and tugging on the nerve. Many people do best on the side opposite the pain, but go with whichever eases your leg.
- On your back with a pillow under your knees. Elevating the knees flattens the lower back gently and can take tension off the nerve root. A rolled towel under the knees works too.
- The supported fetal position helps some people with a herniated disc, as curling slightly can open space in the spine — but it aggravates others, so let your symptoms decide.
What to avoid
- Stomach sleeping, which extends and strains the lower back and tends to worsen nerve compression. (Is it bad to sleep on your stomach?)
- A sagging, too-soft mattress that lets the hips drop and the spine fall out of alignment; firmer support usually helps sciatica.
The red flag you must never ignore
Most sciatica is miserable but not dangerous. However, loss of bladder or bowel control, or numbness in the groin or inner thighs (the "saddle" area), alongside leg symptoms, is a medical emergency (possible cauda equina syndrome) — go to the emergency room, do not wait for morning. Progressive or severe leg weakness also needs urgent evaluation. (How to sleep with lower back pain.)
Supporting the rest of the night
Sciatica pain is amplified by poor sleep, so protect sleep quality while the nerve calms down, and treat the underlying cause with your doctor or physical therapist. (Sleep and chronic pain.)

FAQ
What is the best sleeping position for sciatica? Side-sleeping with a pillow between the knees to keep the hips and spine aligned, or lying on your back with a pillow under the knees to take tension off the nerve root, are usually best. A supported fetal position helps some people with a herniated disc but aggravates others, so let your symptoms guide you.
Why is sciatica worse at night? Lying down and staying still can increase compression on the irritated sciatic nerve, especially in positions that twist the pelvis or let the spine sag, and there are fewer distractions from the pain. The right supported positions decompress the nerve, while stomach sleeping and a too-soft mattress tend to make it worse.
Should I avoid any positions with sciatica? Avoid stomach sleeping, which extends and strains the lower back and worsens nerve compression, and avoid a sagging, too-soft mattress that lets the hips drop out of alignment. Firmer support and a pillow between or under the knees generally ease sciatica more than soft, unsupported surfaces.
When is sciatica an emergency? Loss of bladder or bowel control, or numbness in the groin or inner-thigh "saddle" area along with leg symptoms, is a medical emergency (possible cauda equina syndrome) that needs the emergency room immediately. Progressive or severe leg weakness also requires urgent evaluation. Most sciatica is not dangerous, but these signs are.
The bottom line
To sleep with sciatica, decompress the nerve: side-sleeping with a pillow between the knees or back-sleeping with a pillow under them, on a supportive mattress, and never on your stomach. Most sciatica is painful but not dangerous — but saddle numbness or loss of bladder or bowel control is an emergency. Protect your overall sleep while you treat the cause with a professional.
