Rotator Cuff Tendonitis


One of the most important groups of muscles of the shoulder, the rotator cuff is a series of muscles and tendons that hold the upper arm bone in the shoulder socket. A rotator cuff tear can feel like a dull ache in the shoulder area. This type of injury is common in people who perform overhead motions in their jobs or when playing sports. Risk of rotator cuff injury increases substantially with age.
