Lateral Epicondylitis/Extensor Tendon Injury.

Pain over the lateral aspect of the elbow without nerve injury or elbow instability often is diagnosed as lateral epicondylitis or, colloquially, tennis elbow. It is a common complaint, seen most frequently in women between ages 40 and 60, although it is common in men too. Typical presenting symptoms include pain with prolonged wrist extension activities, pain with resisted wrist or elbow extension, and pain at rest radiating from the elbow along the dorsum of the forearm.
