Rule one: stay off the sore side
The Sleep Foundation's rule of thumb for side sleepers with pain in one shoulder is to avoid lying on the affected side. University of Iowa Health Care gives the same advice: avoid lying directly on the painful shoulder, and sleep on your back or on your non-painful side.
That puts the sore shoulder on top. The problem then becomes the top arm. Without support, it drops forward across your chest and drags the shoulder joint with it, which is often what wakes people up.
Step-by-step side sleeping setup
- Head pillow at the right height. Choose one that keeps your neck level with the mattress. Cleveland Clinic advises a pillow height that keeps your head in a neutral position to reduce strain on your neck.
- A pillow for the top arm. Cleveland Clinic's physical therapist suggests building a pillow wall in front of you, roughly the height of your body, and resting the injured arm on it so the sore shoulder stays supported. A firm body pillow does the same job in one piece.
- A pillow under the armpit if needed. The Sleep Foundation suggests a pillow under the armpit of the sore shoulder, which stays on top, plus one hugged against the stomach.
- A pillow between the knees. The Sleep Foundation includes this in its setup, and Cleveland Clinic says it helps stop the upper leg from pulling forward and twisting your torso.
Which pillow types help
| Pillow | Job | Trade-off |
|---|---|---|
| Firm body pillow or hug pillow | Holds the sore top arm level | Takes bed space |
| Medium to high loft head pillow | Keeps the neck level so the bottom shoulder is not crushed | Must match your shoulder width |
| Wedge pillow | Raises the upper body for semi-upright rest | Not everyone can sleep inclined |
| Shoulder cutout pillow | Lets the bottom shoulder slide under the pillow edge | Helps the bottom shoulder, not the sore top one |
The Sleep Foundation says support is often key for shoulder pain, so a firmer pillow may help, but too much firmness brings its own pressure points. For the cutout design, see shoulder pillows for side sleepers.
When side sleeping is not the answer
Sometimes any side position hurts. The Sleep Foundation calls back sleeping often the best position for shoulder pain because it keeps pressure off both shoulders. Cleveland Clinic suggests resting the arm on a folded blanket or low pillow when on your back so the shoulder does not sag, and keeping the elbow from dropping.
University of Iowa Health Care also suggests trying a recliner or a semi-upright position with pillows propped behind your back, since lying flat changes how the shoulder rests. A wedge pillow is one way to do that in bed. The Sleep Foundation and Cleveland Clinic also warn against stomach sleeping, which strains the arm and shoulder.
Mistakes that keep the shoulder sore
- Arm under the pillow. Cleveland Clinic notes that people who sleep face down often tuck an arm under the pillow, which it says sets the stage for rotator cuff problems.
- A pillow that is too low. Your head tips down and your bottom shoulder takes more weight.
- Waiting too long. University of Iowa Health Care suggests getting checked if pain lasts one or two weeks despite home care or regularly wakes you.
If neck pain is part of the picture, our neck and shoulder pain pillow plan covers both.
What to look for when you buy
Firm hug pillow or short body pillow
Best for: Side sleepers whose sore top arm drops forward
Cleveland Clinic suggests resting the injured arm on a pillow wall in front of you, roughly the height of your body. A firm hug pillow does that in one piece.
Watch out: Too soft and the arm still sinks. Choose a fill that holds its shape.

Best for: Side sleepers whose bottom shoulder feels crushed
A pillow that keeps the neck level lets the head carry its own weight instead of pressing the bottom shoulder into the mattress.
Watch out: Height must match your shoulder width. Adjustable fill makes that easier.
See options on AmazonFoam wedge pillow
Best for: Nights when lying flat on either side hurts
University of Iowa Health Care suggests a recliner or semi-upright position with pillows behind your back; a wedge gives that incline in bed.
Watch out: You may slide down during the night. A knee pillow or bolster under the knees helps.

Best for: Side sleepers whose top leg pulls them forward
Cleveland Clinic says a pillow between the legs can help stop the upper leg pulling forward and twisting your torso.
Watch out: It does not support the arm; use it alongside a hug pillow.
