Tendinitis is inflammation or irritation of a tendon — any one of the thick fibrous cords that attaches muscle to bone. The condition causes pain and tenderness just outside a joint.

While tendinitis can occur in any of your body's tendons, it's most common around your shoulders, elbows, wrists, knees and heels.

Some common names for various tendinitis problems are:

  • Tennis elbow
  • Golfer's elbow
  • Pitcher's shoulder
  • Swimmer's shoulder
  • Jumper's knee

If tendinitis is severe and leads to the rupture of a tendon, you may need surgical repair. But most cases of tendinitis can be successfully treated with rest, physical therapy and medications to reduce pain.
