Rotator Cuff Injury
The rotator cuff is a group of tendons and muscles, which attach the upper arm to the shoulder blade. It helps you lift, push, pull, throw and reach with the arm. The rotator cuff is a common cause of shoulder pain. Pain due to the rotator cuff can occur when the muscles and tendons are inflamed, compressed, or torn. Injury to the rotator cuff is more likely to occur with physical activities that require repeated overhead movement (above shoulder level) such as tennis, golf, swimming, weight lifting or overhead work. The tendon of the supraspinatus, one of the rotator cuff muscles, passes beneath the bone, which you feel on the top of the shoulder, called the acromion. In some individuals, the space beneath the acromion is quite narrow or can narrow due to faulty shoulder movement, injury or inflammation. This can cause the rotator cuff tendon to be compressed or impinged when the arm is raised, which may be painful. If impingement persist it can lead to swelling and adhesions/scarring of the rotator cuff. In severe or traumatic cases it may lead to a muscle or tendon tear. Common Symptoms of a rotator cuff injuryPain primarily on top and in front of the shoulder, sometimes it can be felt at the side of the shoulder. Usually it is worse with overhead activities. The pain can also make it difficult to sleep on the affected shoulder. Weakness may be felt, especially with overhead activities Popping: bursitis or tight soft tissues which may occur with a rotator cuff injury can cause mild popping or crackling sensations in the shoulder.
