Bump near my left knee?

What is the cause of my knee pain?

• - A couple years ago I had sharp pains underneath the kneecap and got it checked out by a physical therapist. Turns out it was Osgood Schlatters. I got a little knee brace to strap underneath the knee and all was fine. After a while the brace was lost, but the pain went away. - Then later my heels started hurting.. they swelled up and were a little whitish, but there was no bruise and I did not bump it on anything. Again it was a sharp pain when I jumped or bent it enough. - About a month and a half ago I notice a little bump on the inside of my left knee. There was no bruise, but it hurt like a bruise when I pressed on it, and it moved. I thought it was a cyst that would go away on its own, so I ignored it. - These past couple weeks I have been getting VERY sharp pains on the inside of me knee where that big bone is. It seems to shoot around there and underneath my knee. The little bump still seems to be there, I just can't see it as well as before, and it feels almost as if it has attached. The pain is not consistent, but hurts once a while, usually once a day when I walk, jump, or bend my knees all the way back. Sometimes the pain is so quick, painful, and surprising that it causes tears to come to my eyes. Does anyone out there know what is causing this pain, and if it is related to my previous heel and knee pains? If any doctors out there know I would appreciate the answer.

  Man I wish I had an answer but i would try and see a really good doctor and tell them what first happened and basically the whole history of it because that is not normal
