Shoulder pain (commonly called Rotator Cuff Tendonitis) presents as soreness, tension, weakness and / or stiffness in the shoulder, shoulder girdle region or upper arm. It is often aggravated by shoulder movement and overhead activities (eg, drying your hair), and can be related to neck pain and dysfunction.

Shoulder pain can be caused by inflammation of any of the shoulder joints, ligaments, muscles, or tendons; additional pain sources are the neck (discs / joints / soft tissues) and arm (mostly soft tissues). The condition may arise due to trauma, prolonged or repetitive overuse (sports), or unaccustomed exertion of the shoulder (DIY / gardening on the weekend).
