Tendons are structures that connect muscles to bone. Tendonitis is an inflammation on tendons.


Tendonitis most commonly occurs from overuse. Tendonitis can occur from an incrase in activity level or due to age related changes in tendons. As people age, tendons loose their elasticity and ability to glide smoothly. The cause of these age-related changes is not entirely understood. Injury resulting in alteration of the gliding path of a tendon may also result in irritation of the tendon.

Evaluation & Treatment

Evaluation of tendonitis begins with a medical history and physical exam. Findings include tenderness or swelling over the tendon and pain with motion. X-rays and MRIs are not usually needed for the diagnosis.

Treatment of tendonitis includes rest, anti-inflammatory medication, ice, cross training, and physical therapy.
