Elbow Pain
To fully understand the sources of elbow pain, it helps to have a basic understanding of the anatomy of the elbow. The elbow is a joint that connects the humerus bone in the upper arm and the ulna and radius bones of the forearm. It operates much like a hinge, with the bicep muscle of the upper arm allowing flexion and the triceps enabling extension.

Epicondylitis
Epicondylitis is a term that refers to the inflammation of tendons surrounding the elbow. It occurs in two forms, medial epicondylitis (golfer elbow) and lateral epicondylitis (tennis elbow), both of which have common underlying sources. Although the conditions engender considerable pain and impairment, they are receptive to treatment and efficacious interventions are available.

Golfer Elbow
Individuals who suffer from golfer elbow know exactly how painful it can be. Known in medical circles as medial epicondylitis, the injury is caused by repetitive stress and strain in the forearm. As the adjacent tendons grow inflamed, they cause pain at the bony juncture where muscle and tendon meet. This in turn causes pain in the inner elbow.
