A rotator cuff injury occurs when the group of muscles and tendons that stabilize the shoulder joint becomes damaged. This can happen due to overuse, trauma, or age-related wear and tear. Symptoms often include pain, weakness, and limited range of motion in the shoulder, making everyday activities difficult. Treatment for a rotator cuff injury may involve 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 care are essential for effective recovery and to prevent further complications.
