Tennis Elbow (Lateral Epicondylitis)

A commonly occurring disorder causing discomfort and tenderness on the outside of the elbow is tennis elbow, sometimes referred to as lateral epicondylitis. Repetitive strain and overuse of the forearm muscles and tendons—especially those related to wrist extension and gripping—cause it. Though the term suggests just tennis players, anyone who performs repeated arm motions—including carpenters, painters, and office workers—can suffer.
The disorder starts slowly and first causes moderate discomfort that gets worse with time. Simple tasks like shaking hands, lifting objects, turning doorknobs, or even carrying a cup could cause pain. Usually, the soreness is concentrated around the bone hump on the outside elbow—the lateral epicondyle.
Clinical symptoms and physical examination define diagnosis; imaging studies are used to rule out other problems. Usually, treatment consists of rest, ice application, anti-inflammatory drugs, and physical therapy emphasizing stretching and strengthening exercises. Patients who are recalcitrant may benefit from platelet-rich plasma (PRP) treatment or corticosteroid injections. Most people recover completely and can resume their usual activities free from long-term consequences with early therapy and activity moderation. Correct technique, ergonomics, and strengthening exercises constitute part of preventive actions.
