Tennis Elbow (Lateral Epicondylitis): Tennis elbow is a common condition characterized by pain on the outer part of the elbow. It typically results from repetitive strain or overuse of the forearm muscles, often due to activities that involve gripping or twisting motions. The pain stems from inflammation or microtears in the tendons that attach to the lateral epicondyle of the humerus.

Golfer's Elbow (Medial Epicondylitis): Golfer's elbow is similar to tennis elbow but occurs on the inner side of the elbow. It involves pain and inflammation of the tendons attached to the medial epicondyle of the humerus. This condition often arises from repetitive stress or overuse of the forearm muscles, especially those involved in wrist flexion and gripping. Despite the name, it is not exclusive to golfers and can affect anyone engaged in activities that strain the forearm.
