Golfer's Elbow, or medial epicondylitis, is an injury to the tendons on the inside of the elbow and muscles of the forearm (those in line with the palm of your hand) which can result from excessive force being used to bend the wrist. Despite its name, it’s not only a golfer problem; any activity which requires great force applied to the wrist can cause the condition. Hard throwing motions are a frequent cause, leading Golfer’s Elbow to occasionally be known as Baseball Elbow.
