Medial epicondylitis, more commonly known as golfer’s elbow, causes pain where the flexor muscles of the wrist and fingers attach to the bone on the inner side of the elbow. This pain tends to increase when bending the wrist or during pronation (internal wrist rotation). An ultrasound or MRI is needed to diagnose this condition. It is important to make sure that the patient does not have ulnar nerve entrapment or a ligament issue (which are common in athletes).
