Greg Is Somewhat of a "Weekend Athlete" Who Has Overextended

Essay

Greg is somewhat of a "weekend athlete" who has overextended himself by pitching baseball for a local team during the week and playing golf on the weekends for several hours. He presented himself to the emergency room last week with severe shoulder pain (at the glenohumeral joint). The physician told him that the X ray was not conclusive, but he may have damage to his rotator cuff. What is the rotator cuff, and how might he have caused this damage? What remedies will the physician recommend?
