The rotator cuff is a series of four muscles that rotate the shoulder allowing one to throw a ball, reach up, comb hair, brush teeth, scratch the back and take a container out of the refrigerator and pour.  Rotator cuff problems can be from injury or from wear and tear.  Patients will frequently complain of difficulty reaching into the backseat of a car and night pain when rolling over onto the shoulder.  Evaluation in our office will determine the exact cause and plan of treatment.
