Why do i experience elbow pain when sleeping on my side?

Reviewed by Tomas Diaz, MD

Emergency Medicine

Sleeping on your side puts pressure on your elbow, which can irritate tendons and nerves and cause pain.

Explanation

Side sleeping can strain your elbow by compressing muscles, tendons, and nerves. This position may worsen existing conditions like tennis elbow or cubital tunnel syndrome—where the ulnar nerve becomes pinched. Poor sleep positioning may lead to elbow joint inflammation and discomfort. To minimize pain, try using a soft cushion or adjust your sleeping position to reduce pressure on your elbow. A healthcare professional can provide additional recommendations for your specific case.
