Tendinitis

Alternative Names

Calcific tendinitis; Bicipital tendinitis

Definition of Tendinitis

Tendinitis is inflammation, irritation, and swelling of a tendon, which is the fibrous structure that joins muscle to bone. In many cases, tendinosis (tendon degeneration) is also present.

Causes, incidence, and risk factors

Tendinitis can occur as a result of injury, overuse, or with aging as the tendon loses elasticity. It can also be seen in persons with body-wide (systemic) diseases such as or diabetes.

Signs and tests

The health care provider will perform a physical exam and look for signs of pain and tenderness when the muscle attached to the tendon is used against resistance. There are specific tests for specific tendons.

Treatment

The goal of treatment is to relieve pain and reduce inflammation.

Expectations (prognosis)

Symptoms improve with treatment and rest. If the injury is caused by overuse, a change in work habits may be indicated to prevent recurrence of the problem.
