Medial epicondylitis is commonly called a golfer’s elbow or thrower’s elbow. It is a condition that develops when the tendons on the inside of the forearm become irritated, inflamed, and painful. Repetitive use of the hand, wrist, forearm, and elbow causes the golfer’s elbow. This condition often gets diagnosed in people who repeatedly swing a golf club or other activities that require gripping, twisting, or throwing. Using a computer or performing yard work also can cause the condition. Athletes who perform overhead motions, carpenters, and plumbers are most at risk. Golfer’s elbow is most common in men over the age of 35.
