A rotator cuff injury involves damage to a group of muscles and tendons that stabilize the shoulder joint. These injuries can occur due to overuse, trauma, or age-related wear and tear. Symptoms often include pain, weakness, and limited range of motion in the shoulder. Treatment for rotator cuff injuries may include rest, physical therapy, and anti-inflammatory medications. In more severe cases, surgical intervention might be necessary to repair the damaged tendons. Early diagnosis and appropriate management are essential for recovery and to prevent further complications.
