Causes of Elbow Pain. Elbow pain is sometimes due to arthritis, but in general, most elbow pain results from overuse injuries. Sports or any activities and professions that require repetitive hand, wrist or arm movements are more prone to elbow injury. Common causes of elbow pain are bursitis, elbow strains, and arthritis.
The common structures that cause anterior elbow pain are the biceps muscle and tendon. The biceps muscle is so called because it has two origins (short and long head) and two muscle bodies. The short head of biceps originates from the coracoid process of the scapula and is rarely affected by tendinopathy or injury.
