Tennis Elbow

What is tennis elbow?

Tennis elbow, or lateral epicondylitis, is an injury to the tendons along the outer elbow. The inflammation from this injury can cause pain, weakness, aching and tightness. The muscles that open the fingers and extend the wrist all combine to form a common tendon along the outside of the elbow. In tennis elbow, inflammation or tearing of this tendon causes pain with use of the hand and arm.
