Where does tennis elbow tendinopathy cause pain?

Tennis elbow, clinically known as lateral epicondylitis, is characterized by pain that originates in the region of the lateral epicondyle of the humerus. This condition is typically caused by the overuse of the extensor muscles of the forearm, leading to microtears and degeneration of the tendons associated with these muscles. The pain is often exacerbated by activities that involve wrist extension and gripping.

In contrast to the lateral epicondyle, other areas such as the medial epicondyle are associated with medial epicondylitis (also known as golfer's elbow), which involves the flexor tendons. The radial tuberosity is related to the biceps tendon, and the olecranon process is part of the ulna and commonly involves different types of conditions, such as triceps tendinopathy or bursitis. Thus, the pain directly associated with tennis elbow is specifically localized to the lateral epicondyle, confirming that this is the correct site related to the condition.
