What is the typical symptom of lateral epicondylitis?

Lateral epicondylitis, commonly referred to as tennis elbow, is characterized by pain and tenderness at the lateral epicondyle of the humerus. This condition arises due to overuse of the forearm muscles and tendons near the elbow joint, which leads to inflammation and micro-tearing of the extensor tendons, particularly the extensor carpi radialis brevis. Patients typically report pain that worsens with activities that involve wrist extension or gripping, which makes the site of pain, the lateral epicondyle, a hallmark symptom of the condition. Recognizing this symptom is critical for diagnosis and appropriate management of the injury.
