A rotator cuff injury is a common shoulder injury that affects the muscles and tendons surrounding the shoulder joint. It can occur from repetitive overhead motions, trauma, or degenerative changes. Symptoms of a rotator cuff injury include shoulder pain, weakness, decreased range of motion, and difficulty performing everyday tasks. Treatment options for a rotator cuff injury may include rest, physical therapy, pain medication, and in some cases, surgery. Early diagnosis and appropriate treatment are important in order to relieve symptoms, regain strength and function, and prevent further damage to the rotator cuff.
