This condition is an irritation or inflammation of the biceps tendon at the shoulder. The biceps tendon helps to stabilize the humerus and aids in activities that involve overhead motion such as tennis or throwing a ball.

This condition usually results from stress on the shoulder joint caused by repetitive overhead motion. Sports such as tennis and baseball are common culprits. Age may also be a factor. Over time, this inflammation can cause deterioration of the biceps tendon, resulting in tears and, in severe cases, rupture.

Pain is the primary symptom, particularly when the arm is bent at the shoulder or during overhead movements. Other symptoms can include tenderness of the shoulder, bruising, swelling, and a popping or snapping sound during movement of the upper arm.

Treatment options include rest, cold compress, anti-inflammatory medications, injections, stretching exercises and physical therapy. Severe cases may require surgery.
