An overuse injury common among swimmers and others, such as throwers, who make repeated, vigorous movements of the arms. It is characterized by inflammation and intense pain when the arm is lifted upwards and forwards. Soft tissues, mostly the tendons associated with rotator muscles of the shoulder joint, become trapped in the space between the head of the humerus and the shoulder blade. The injury can be prevented by a good upper body conditioning programme, including both strength and flexibility exercises, combined with the development of good technique. Established injuries usually respond to rest, ice, and anti-inflammatories, but surgery may be required in severe cases.
