Golfer’s elbow, also known as medial epicondylitis, is a painful condition that occurs when a tendon near the elbow is subjected to repetitive forces. While this issue may occur in golfers, it can happen to anyone and cause pain that spans from the wrist to the elbow on the inside of your arm.
The presence of these symptoms often suggests you have medial epicondylitis. However, these complaints can also point to a more serious condition like an avulsion fracture (when a bone fracture attached to a ligament or tendon separates from the rest of the bone) or an ulnar collateral ligament injury (injury to a ligament on the inside of the elbow).
