Tendonitis is a condition in which a tendon becomes inflamed. When the smooth, gliding motion of your tendon becomes impaired, the tendon itself becomes irritated and movement becomes painful. Tendonitis is often an overuse injury, especially with starting a new activity or exercise. Tennis elbow (or epicondylitis) is a common type of tendonitis.
Laser therapy can help by improving circulation to the affected area and removing the inflammation that afflicts the tendon. Once the area is no longer inflamed, the tendon will once again move smoothly and no longer cause pain when used.
