  • The difference between golfer's elbow and tennis elbow lies in where the elbow is inflamed. Both tennis elbow and golfer's elbow are forms of epicondylitis, an inflammation of tendons that attach to the elbow. Tennis elbow affects the lateral, or outside, epicondyle and golfer's elbow affects the medial, or inside, epicondyle.
