Tennis Elbow Symptoms and Causes
Lateral epicondylitis, also known as tennis elbow, is characterized by pain on the outside (lateral side) of the elbow. The pain is caused by damage to the tendons that bend the wrist backward away from the palm. Tennis elbow, as the name implies, often is caused by the force of the tennis racket hitting balls in the backhand position. The forearm muscles, which attach to the outside of the elbow, may become sore from excessive strain. When making a backhand stroke in tennis, or making a similar motion with similar tools, the tendons that roll over the end of the elbow can become damaged.
