Calcific Tendonitis

The rotator cuff is comprised of four muscles which have tendons that cover the head of the upper arm bone (humerus). It is responsible for movement and strength of the shoulder joint, as well as stabilizing the arm in the joint socket.


The rotator cuff functions in the rotation of the shoulder and lifting of the arm. When the tendon becomes irritated or inflamed this is commonly known as rotator cuff tendonitis. Some patients have calcium deposits in their rotator cuff which makes the rotator cuff susceptible to becoming inflamed. When tendinitis happens in this setting, it is called calcific tendinitis. 

Symptoms of calcific tendonitis include pain, stiffness and/or weakness of the shoulder. Pain will often be felt in the front or side of the shoulder and can radiate down the arm or up towards the neck. Losing strength or motion in the arm can create difficulty in basic daily activities. It can also be extremely painful at night when lying in bed.
