How to Sleep With Sciatica: Positions and Tips That May Help

By the GSMC pain management team, medically reviewed by Dharam P. Mann, MD

Sciatica often feels worse at night. Lying still, rolling over or getting out of bed can send pain down the back of your leg, and a poor night of sleep can make the next day harder. The good news is that small changes in how you lie and how you support your body may help you rest more comfortably.

This is Day 2 of our sciatica series. If you missed Day 1, start with our guide to sciatica treatment options.

Why sciatica can feel worse at night

Sciatica happens when a nerve root in the low back is pinched or irritated, often by a herniated disc or spinal stenosis. Some sleep positions twist the spine or arch the low back, which can add pressure on that nerve. A soft mattress that lets your hips sink can do the same. Lying still for hours can also leave you stiff when you first move in the morning.

Sleep positions that may help

On your side with a pillow between your knees

Lie on the side that hurts less, bend your knees slightly and place a firm pillow between your knees. This keeps your hips, pelvis and spine lined up and may take strain off the irritated nerve. A small pillow under your waist can help if there is a gap between your side and the mattress.

On your back with your knees supported

Lie on your back with one or two pillows under your knees. Bending the knees flattens the low back slightly, which many people with sciatica find more comfortable. A thin pillow under your head keeps your neck neutral.

In a gentle fetal position

If your sciatica comes from a herniated disc, curling up on your side with your knees drawn gently toward your chest may open space between the vertebrae. Keep the curl relaxed rather than tight, and switch sides during the night if you can.

Positions many people find harder

Sleeping on your stomach tends to arch the low back and twist the neck. If it is the only way you can fall asleep, put a flat pillow under your hips and lower belly to reduce the arch.

Tips for a more comfortable night

• Choose a medium-firm mattress that supports your hips. A firm mattress topper or a plywood board under a sagging mattress can help in the short term.
• Get in and out of bed with a log roll: roll onto your side, drop your legs over the edge and push up with your arms, keeping your back straight.
• Try heat or ice for 15 to 20 minutes before bed. See our heat and ice self-care guide.
• Take a short, easy walk in the evening and avoid sitting for long periods before bed.
• Keep a regular sleep schedule and a cool, dark room. More ideas are in our sleep and pain page.
• Gentle stretches recommended by your physical therapist may ease tension before you lie down. Stop if a stretch makes leg pain worse.

When to see a doctor

Most sciatica improves over a few weeks. Make an appointment if pain keeps waking you at night for more than a week or two, if it is getting worse, or if you have numbness or weakness in your leg or foot.

Go to the emergency room or call 911 if sciatica comes with loss of bladder or bowel control, numbness in the groin or saddle area, or leg weakness that is getting worse quickly.

Frequently Asked Questions

What sleeping position helps with sciatica?

Many people find side sleeping with a pillow between the knees, or back sleeping with pillows under the knees, more comfortable. The right position depends on the cause of your sciatica, so try a few and notice which one eases leg pain.

Should I sleep on a firm or soft mattress with sciatica?

A medium-firm mattress that keeps your hips from sinking is often more comfortable than a very soft one. A firm topper can help in the short term.

Why does my sciatica hurt more at night?

Some positions twist or arch the low back and add pressure on the irritated nerve, and lying still for hours can cause stiffness. Adjusting your position and support may help.
