You should go see an orthopedist. (Honestly, if the orthopedist doesn't help you should also go see a rheumatologist to rule out juvenile rheumatoid arthritis. I'm guessing it is not this because JRA will switch from one leg to the other, one knee to the other.) The orthopedist is a specialist who will try to find out what is wrong and why you are having pain. Both my kids have had to go to an orthopedist...my son was having foot pain and had to wear a "boot" for a couple weeks and then do exercises. Another time he had tweaked his knee and we were given instructions on what to do to get it to heal. My daughter had inflamed growth plates in her heel once which you eventually outgrow but they had her ice it and wear gel pads in her shoes.
