Lateral epicondylitis or lateral epicondylalgia, known colloquially as tennis elbow, shooter's elbow, and archer's elbow or simply lateral elbow pain, is a condition where the outer part of the elbow becomes sore and tender. Since the pathogenesis of this condition is still unknown, there is no single agreed name. While the common name 'tennis elbow' suggests a strong link to racquet sports, this condition can also be caused by sports such as swimming and climbing, the work of manual workers and waiters, as well as activities of daily living. Tennis elbow is an overuse injury occurring in the lateral side of the elbow region, but more specifically it occurs at the common extensor tendon that originates from the lateral epicondyle. The acute pain that a person might feel occurs as one fully extends the arm. In one study, data was collected from 113 patients who had tennis elbow, and the main factor common to them all was overexertion.
