What is the 'pillow canal' and how does it help shoulder pain?
The pillow canal uses a small throw pillow placed between your head and the shoulder so your head and thoracic area take the weight instead of the shoulder, reducing pressure and irritation.
Why is sleeping with my arm overhead or on my stomach bad for an injured shoulder?
Arms overhead or stomach sleeping internally rotates and impinges the shoulder, increases joint pressure, can cut circulation, and often worsens pain overnight.
How many pillows should I use if I must sleep on my sore side?
One small throw pillow plus your regular pillow can form a canal; for arm support use two pillows—one under the arm and one in the armpit—to keep the shoulder in a neutral, less stressful position.
Will changing my sleep position help my shoulder heal?
Yes—reducing sustained pressure and keeping the joint more neutral helps prevent impingement and supports healing, though persistent or severe pain should be evaluated by a healthcare professional.
