How to Sleep With Lower Back Pain: Positions to Try

For lower back pain, try sleeping on your side with a pillow between your knees, or on your back with a pillow under them. Choose the position that feels easier on your body. There is no single sleeping position that suits every cause of back pain.

Start with a pillow you already own. You can adjust its placement before deciding whether you need different bedding.

Where should you put the pillow?

These options follow Mayo Clinic's guidance on sleeping positions for back pain.

Pillow placement for different sleeping positions

Position	What to try
On your side	Bend your knees slightly toward your chest and put a pillow between your legs to help keep your hips and spine aligned.
On your back	Place a pillow under your knees. If needed, try a small rolled towel beneath your waist for additional support.
On your stomach	This position can strain the back. If other positions are uncomfortable, try a pillow under your hips and lower abdomen.

Keep your head pillow comfortable too. Support at your knees will not resolve an awkward neck position. If that is also a problem, see our guide to sleeping with neck pain.

Change one thing at a time

Begin in the position you usually find comfortable and add the suggested support. If the pillow feels too bulky, try a thinner one. If a position increases your pain or causes tingling, stop using it.

You do not have to keep yourself perfectly still all night. The aim is to find a comfortable place to settle and return to when you wake.

For a few mornings, make a brief note of the position you started in, whether pain woke you, and how you felt when getting up. A simple record is more useful than buying several pillows and changing everything at once.

If you have sleep apnea or another condition with specific positioning advice, keep following your treatment plan. A position that feels good for your back may not suit your breathing during sleep.

What else can help at bedtime?

Keep up gentle daily movement as you are able. Spending long periods in bed can make recovery harder; the goal is to balance comfortable activity with shorter periods of rest. Follow any exercise restrictions your clinician has given you.

If you already have a treatment plan, keep its instructions accessible so you are not guessing about exercises or medicines when you are tired. Do not add sedating medicines simply to sleep through unexplained pain.

A mattress change is a larger decision than a pillow adjustment. If you are considering one, think about what feels comfortable, whether your current mattress has an obvious sag, and the return policy. An expensive mattress cannot guarantee relief.

When is it more than a sleep-position problem?

Arrange an assessment if pain keeps disrupting sleep, is worsening, or is not improving with home care. Fever, unexplained weight loss, or pain after an injury also deserve medical attention.

Get emergency care for back pain with new loss of bladder or bowel control, difficulty urinating, numbness around the genitals or anus, or weakness or numbness in both legs. These are among the urgent warning signs in NHS back-pain guidance. Do not wait to see whether a different pillow helps.
