What do you suggest if I am 19 yrs old and I think I have osgood schlatter's disease?

See your doc. After growth plates close in adolescence, this condition will heal spontaneously.Most patients if treated conservatively with rest and NSAIDS will be pain-free within 12 months. This is a self-limiting condition but can last years if not treated appropriately.Some adults who had severe disease in adolescence will continue to have some knee pain (usually with kneeling) many years into adulthood.
