I would also suggest to you that you do stretches that do NOT bend the knee back. I know many runners do this because I see it often. That will kink your peroneal nerve dramatically.
I'd do lunge stretches against a wall instead.

There are also hamstring stretches for the leg/knee, where you elevate the leg,
heel on a support like a step, and stretch the leg out and bend as far as you feel comfortable. This realigns the knee and was a great stretch for me when my knee dislocated years ago.

So you have some time to try to improve your issues yourself.
Once you get a CMT diagnosis, you know, there is nothing you can do about at this time. Most suggestions would be like you are hearing from Kitt and Suzanne here. At least you only have tingling... which is only a beginning. Tingling is common for most people. Everyone gets some now and then.
