Ive been having pain under where my kneecaps are at not where the kneecap is but lik an inch below.what is it?

o my science teacher had the same problem of course there is always a chance for diffrences but this is exactly what happened to him anyway he is an athletic person and he wore away the cartaloug between his knee and leg bones anyway you two bones are scraping together- GO TO THE DOCTOR he had to get cartaloue from a dead man to replace his own loss its pretty serious. GO TO THE DOCTOR!!!!! or you could have arthritous?

patella strain. the only way to really know is to get a consult with an orthopedic surgeon. i had knee pain, and consider my decision to see a doc the best thing i did to fix my damaged knee.
