What Is the Best Sleeping Position for Shoulder Pain?

For most people with a sore shoulder, the most comfortable position is lying on the back with a pillow under the painful arm, or lying on the pain-free side while hugging a pillow so the sore arm rests forward. Lying directly on the painful shoulder tends to be hardest. No trial has compared positions head to head, so choose the one that keeps your shoulder supported and lets you sleep.

Key takeaways

• Night pain is very common in rotator cuff problems. A systematic review of 10 studies reported nighttime pain in 91% to 93% of patients.
• In a small Danish study, 67% of people with one painful shoulder who slept on one side lay on the painful shoulder.
• In a series of 58 people with significant rotator cuff tears, 52 were side sleepers.
• We found no randomized trial that names a single best position, so the tips below combine research with common clinical advice.
• Pain that wakes you every night, comes with fever, or spreads with numbness or weakness is a reason to call your clinician.

If your pain is mostly at night, our post on why shoulder pain gets worse at night explains the likely causes. This post focuses on how to lie down.

Why does sleep position matter for a sore shoulder?

AAOS OrthoInfo lists pain at rest and at night, especially when lying on the affected shoulder, among the most common symptoms of a rotator cuff tear. The same page notes that some tears do not hurt at all, so pain is not a perfect guide to what is going on inside the shoulder.

Night pain is a frequent reason people seek care. A 2022 systematic review by Castro-Contreras and Valdez-Pardo pooled 10 studies with 1,516 patients and reported that nighttime pain affected 91% to 93% of them, with an average intensity of 5.5 on a 10 point scale. Every included study reported changes in sleep quality. The authors suggested that poor sleep reflects altered shoulder function as well as pain. A 2019 systematic review by Longo and colleagues found that most people with rotator cuff tears had a sleep disturbance and that sleep quality tracked with pain. Night position was one of the factors that appeared to matter.

In a 2022 prospective study by Dolan and colleagues of 326 people having arthroscopic rotator cuff repair, 89% reported sleep disturbance before surgery. Of the patients whose sleep problems resolved, 46% reported resolution by 3 months after surgery, another 31% by 6 months, and the rest by 12 or 24 months. A 2024 review by Daher and colleagues calls sleep disturbance one of the most common complaints in rotator cuff disease and notes that research on the link is still limited and inconsistent.

Which sleeping positions do people with shoulder pain actually use?

Two small studies give a picture of real habits.

• A 2012 cross-sectional study by Kempf and Kongsted asked 83 Danish adults with pain in one shoulder about their sleep. Among those who slept on one side, 67% lay on the painful shoulder. The authors noted that the link may not be causal, and they suggested it is worth testing whether a change in sleeping position helps.
• A 2024 case series by Richards and colleagues looked at 58 patients with a partial thickness tear of more than 50% or a full thickness tear. Of these, 52 were side sleepers, 4 were stomach sleepers, 1 was a back sleeper, and 1 used all three positions. The authors concluded that tears were most often seen in side sleepers. This was a clinic series without a comparison group, so it cannot show that side sleeping causes tears.

Both studies show that many people with shoulder pain sleep on their side, and many lie on the sore shoulder. They do not show which position heals best. Pressure on a tender shoulder is one reason that lying on it can hurt, and that is a reasonable thing to avoid while you wait to be seen.

What can you try, position by position?

The ideas below are practical suggestions for comfort. We found no trial testing them against each other, so adjust them to what works for you.

Back sleeping with arm support

Lying on your back keeps weight off both shoulders. Many people feel better with a small pillow or folded towel under the painful upper arm and forearm, so the arm rests level with the body and the shoulder does not sag backward into the mattress. A second pillow under the head keeps the neck comfortable. Some people add a pillow under the knees to relax the lower back.

After rotator cuff repair, back sleeping is common. In a 2026 prospective study by Fiandeiro and colleagues of 63 patients, back sleeping rose from 39.2% before surgery to 85% at 2 weeks, while side sleeping fell from 64.7% to 27.5%. By 6 weeks side sleeping had partly returned, and by 24 weeks sleep positions looked like they did before surgery. Our guide on how to sleep after rotator cuff surgery covers that stage in detail.

Side sleeping on the pain-free side

If you cannot sleep on your back, lie on the side opposite the sore shoulder. Hug a firm pillow against your chest and rest the painful arm on top of it, so the arm stays slightly forward and does not hang across the body. A pillow between the knees can keep the hips level. Our post on the best pillows for side sleepers with neck and shoulder pain explains pillow height and firmness.

The Fiandeiro study also found that people who were side sleepers before surgery had more pain related waking during recovery. If side sleeping is your habit, expect that changing it may take a few weeks of practice.

Side sleeping on the painful side

This is the position most often linked with night pain, and it is the one most people try to avoid. If you wake up on the painful side, roll back, reset your pillows, and try again. A pillow against your back can make it harder to roll onto the sore side without noticing.

Semi-reclined sleeping

Some people find a reclined position easier when pain is intense, because it avoids lying flat and keeps the shoulder in a neutral spot. This is also a common choice early after shoulder surgery. Our post on a recliner or bed after shoulder surgery compares the two setups.

Stomach sleeping

Stomach sleeping often places the arm overhead or twists the neck to one side for hours. For a painful shoulder, many clinicians suggest moving away from it. We found no study that tested this, so treat it as a comfort guideline.

Do pillows and orthopedic supports help?

Evidence for pillows is limited. A 2023 study by Cine followed 72 patients who had surgery for a herniated disc in the neck and had shoulder or arm pain. Pain scores were significantly lower in the group that used orthopedic pillows. The study found no link between sleeping position and shoulder or arm pain in that group. It involved neck surgery patients, so it does not tell us what a pillow does for a rotator cuff problem.

What a support can do is simple. It can hold your arm in a steady position, reduce the chance that you roll onto the sore side, and spread pressure. The Shoulder Sleeper Pillow is designed to support the arm at night with a waist strap, arm strap and wrist strap, and it can help limit unwanted arm rotation while you sleep. It is built for back and side sleepers, comes in Small/Medium and Large/XL sizes, and has left and right versions. If you are comparing a wedge style system with a strap based pillow, our post on MedCline vs Shoulder Sleeper Pillow lays out the differences in position, size and footprint.

A pillow does not diagnose or treat a shoulder problem. If the pain is new, severe, or following an injury, get it checked first.

What else can make nights easier?

• Warm up before bed. Some people sleep better after a warm shower and a few gentle movements that your clinician has approved.
• Check your daytime habits. Long stretches of reaching or lifting can leave a shoulder more irritated by evening.
• Keep a short log. Note which position you fell asleep in, which one you woke up in, and how many times pain woke you. Bring it to your visit.
• Ask about pain medicine timing. If your clinician has approved a pain reliever, ask whether taking it in the evening makes sense for you.

For night pain after surgery, our rotator cuff surgery recovery guide shows how sleep usually changes across the recovery timeline.

When should you call a clinician?

Call your doctor or care team if you notice:

• Shoulder pain that wakes you most nights for more than a couple of weeks
• Pain that follows a fall or injury, or a new loss of strength when lifting the arm
• Numbness, tingling, or weakness that spreads down the arm, which our guide to shoulder pain and numbness in the arm explains in more detail
• Fever, redness, or swelling around the shoulder
• Pain that is steady and does not change with position

Chest pain, shortness of breath, or pain that spreads to the jaw or left arm needs emergency care right away.

Your next step

Tonight, set up two pillows before you get into bed: one under the head and one to rest the sore arm on. Start on your back or on your pain-free side, and write down how you slept. If you want a steadier setup for the arm, take a look at the Shoulder Sleeper Pillow.

Common questions

Should I sleep on the affected shoulder?

Most people find it painful, and lying on a tender shoulder is the position most often linked with night pain. If you wake up on that side, roll back and use a pillow to keep you from returning to it.

Is sleeping on my back better for shoulder pain?

For many people it is more comfortable, because it keeps weight off both shoulders. Support the sore arm with a small pillow so it does not sag backward. No trial has shown that back sleeping heals a shoulder faster.

Can sleeping on my side cause a rotator cuff tear?

Side sleeping is common among people with tears, but the available studies are small and cannot show cause and effect.

How long will shoulder pain keep waking me at night?

It depends on the cause. After rotator cuff repair, studies show sleep usually improves over 3 to 6 months. For other causes, ask your clinician what to expect.

Does a pillow under the arm help?

Many people say it does, because it holds the arm level and reduces strain. We found no trial of this setup, so treat it as practical comfort advice.
