I hurt my knee back in June playing softball. I went to the doctor and he said it was chondromalacia. it's where the bone in your knee right under your kneecap rubs the cartilidge between the 2 bones...that causes pain. i was wondering if anybody ever had this type of problem and what did you do to make it better...it's so bad, i can't even run. walking is fine, but it hurts like a bitch to run or go up/down stairs...any suggestions????
