Tendonitis is inflammation or irritation of a tendon — any one of the thick fibrous cords that attach muscles to bone. The condition, which causes pain and tenderness just outside a joint, is most common around your shoulders, elbows and knees. But tendonitis can also occur in your hips, heels and wrists.
Some common names for tendonitis are tennis elbow, golfer's elbow, pitcher's shoulder, swimmer's shoulder and jumper's knee.
If tendonitis is severe and leads to the rupture of a tendon, you may need surgical repair. But many times, rest and medications to reduce the pain and inflammation of tendonitis may be the only treatments you need. You can also take preventive measures to reduce your chance of developing tendonitis or to keep tendonitis from affecting your normal range of motion in joints such as your shoulder.

Tendons are usually surrounded by a sheath of tissue similar to the lining of the joints (synovium). They're subject to the wear and tear of aging, direct injury and inflammatory diseases. The most common cause of tendonitis is injury or overuse during work or play. The pain is usually the result of a small tear in or inflammation of the tendon that links your muscles to your bone. Tendonitis can also be associated with inflammatory diseases that occur throughout your body, such as rheumatoid arthritis.
