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 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.
