Shoulder impingement occurs when the tendons of the rotator cuff become compressed during shoulder movements. This compression can lead to pain and limited range of motion, especially when lifting the arm overhead. It often results from repetitive overhead activities or structural issues in the shoulder joint. Symptoms of shoulder impingement include pain, weakness, and difficulty performing daily tasks. Treatment options may include rest, physical therapy, and anti-inflammatory medications. In some cases, a doctor may recommend surgery to relieve the pressure on the tendons if conservative treatments are ineffective.
