Thanks for the helpful replies everyone. I actually was at just a regular check-up today and asked about my leg length in relation to each other, my doc immediately said, "your left leg is quite a bit longer than your right leg, didn't you know that?" The problem is I sustained my concussion right in the middle of puberty - so not only was I going through lots of physical and chemical changes because of that, but also the concussion.

Though now I seem to have hit a dilemma, since I am pretty sure my limp is caused by my difference in leg length and possibly my poor knee health, it will probably be unable to fix. I am still concerned about the effect that this will have on my brain health.
