Deltoid/teres cramp?: You may have a cramp or strain of your deltoid or teres muscles. See your family physician and consider tylenol, (acetaminophen) rest, ice, topical massage. If no improvement within a week, you must see an internal medicine and orthopedic specialist for more sinister pathology evaluation. Good luck!
