biceps tendinitisInflammation of the long head of the biceps tendon, which is a common cause of shoulder pain.
Increased activity of biceps or shoulder, especially if repetitious (overuse syndromes); impingement; isolated injury. Secondary causes include compensation for rotator cuff disorders, labral tears and intra-articular pathology. Biceps tendinitis is particularly common in overhead athletes—e.g., baseball pitchers, swimmers, gymnasts, racquet sport enthusiasts, and rowing/kayak athletes.
Aching shoulder pain aggravated by shoulder movement or resisted flexion of biceps muscle. Most patients have not had an acute traumatic event.
