Signs and symptoms of shoulder impingement syndrome include shoulder joint pain with overhead use of the arm, limited range of motion, and joint stiffness. Other associated symptoms can include neck pain, arm pain, and muscle weakness. There is difficulty with reaching the arm overhead or reaching the arm up behind the back. The condition may progress with time to rupture of the muscle.
Causes of impingement syndrome
The cause of impingement syndrome is swelling of the rotator cuff muscles that increases pressure and reduces blood flow to the muscle, ultimately leading to muscle damage.
