When a single or multiple of any of the four shoulder muscles that make up the rotator cuff undergo excessive use, the tendons that attach these to the humerus bone of the uppar arm can become damaged. The tendon is naturally designed to be elastic to help the function of the muscles but, if these are stretched beyong their natural range, the fibrous tissue may give away.
Shoulder tendonitis can occur after injury from a single case of extreme motion or may occur from progressive, repetitive stress that eventually leads to tendon degeneration. The tendon will then become irritation, causing inflammation and swelling.
Tendonitis in the rotator cuff within the shoulder will primarily cause shoulder pain. Shoulder pain associated with the condition may begin as a dull ache and sharpen as the affected individual moves the shoulder, especially while raising the arm overhead.
