Its nothing new for me but I thought yall might have some suggestions. As a kid, teenager, and young adult I had a bad case of Osgood Schlatters disease in my left knee. I was left with a large calcified mass right below my kneecap and the pain never really went away until my early 20s. Marathon training however has brought it back. I cant make the lump go away but there has got to be something I can do about the pain...any suggestions?
