How can I get rid of tendonitis in my leg? Or at least make it feel better.

Diagnosis first! Tendonitis is a non-specific term that is applied to many areas of pain, though it is often not the correct diagnosis. See a sports med doc to be sure. True tendonitis (inflammation of a tendon) improves with rest, ice, and fixing the contributing mechanical factors. Degenerative changes in tendon (cause pain after the inflammation has subsided)=tendonosis. Treat with eccentric strengthening in pt.
