Biceps tendonitis is an inflammation of the tendon located at the long head of the biceps, according to the American Academy of Orthopaedic Surgeons, or AAOS. Tendon degeneration due to age and repetitive overhead motion from routine chores and sports activities, such as swimming and baseball, usually cause the condition.
Symptoms of biceps tendonitis include tenderness in the front of the shoulder that worsens with overhead activity, pain that travels down the upper arm bone and an occasional snapping sound in the shoulder, explains the AAOS. Nonsurgical treatments include resting from overhead activities, applying ice to the affected area and taking nonsteroidal anti-inflammatory medicines. If these treatments do not work, surgical options, such as tendon repair, biceps tenodesis and biceps tenotomy, often restore full range of motion to sufferers.
