Tendonitis is an inflammation or irritation of a tendon, a thick cord that attaches bone to muscle. Tendonitis is most often caused by repetitive, minor impact on the affected area, or from a sudden more serious injury. Anyone can get tendonitis, but it is more common in adults, usually over 40 years of age. As tendons age they tolerate less stress, are less elastic, and are easier to tear.
