Tendinitis is inflammation of the thick fibrous cords that attach muscle to bone. These cords are called tendons. The condition causes pain and tenderness just outside a joint.
Tendinitis can occur in any tendon. But it’s most common around shoulders, elbows, wrists, knees and heels.
Most tendinitis can be treated with rest, physical therapy and medicine to reduce pain. Long-lasting tendon inflammation can cause a tendon to tear. A torn tendon might need surgery.
