What is difference in tendonitis and tendenosis? I am told there is a difference and treatment for one can make the other worse.

Tendons. Tendonitis is an irritation or inflammation of a tendon - cords holding muscle to the bone- that often occurs from a strain or overuse injury. It repsonds to antiinflammatory meds ; decreased use. Tendinosis is degeneration of the tendon causing it not to function well that can occur as a result of an old injury. Treatment is ice and physical therapy.
