i would suggest asking chiropracters (i think i spelled it wrong) if they can do anything, but im sure the MD would have said something if your bone structure was mishaped in some way i would suggest working around it and try to learn to use your left leg more then your right, but you'll still have to work around any pain you get else you could always use punching mainly and ask around (mainly doctors and others like it) to see if there's more alternatives to just surgery personaly i dont know, but these are the things i would try first, i got all kinds of problems, nothing too serious but my left leg grows faster because i use to lean on my right leg all the time, but im self-concious about how i walk (it's nothing too noticable but sometimes it feels like im swaying) then ill probably develop arthiritis in my joints, but i already knew that was coming and i have enough back/neck problems due to having to carry around a heavy backpack in the previous years of school it's bad enough that they have you carry around heavy books for 7 hours a school day, then they make it worse in some years and not as bad in others
