Calcific tendinitis is a condition that occurs when calcium builds up in the tendons. (This may also be called calcific tendinopathy.) Tissue tears and natural tissue breakdown make this more likely to happen.
Calcific tendinitis is most common in the shoulders. But it may occur in the elbows, wrists, hands, hips, knees, or feet. Symptoms may include pain and stiffness, occasional locking of the joint, or limited movement. Pain is often worse at night and may interfere with sleep.
Treatment includes home care such as rest, ice, and medicines to reduce pain and swelling. A doctor may inject steroid medicine into the area to help relieve pain. Some people may have treatments to break up or remove the calcium deposits.
