There are over 100 causes of PN. The hereditary types are only one of those.
If you wear athletic shoes? Even lacing too tightly will numb and then irritate your insteps where most of the nerves are.
There are alternate ways to lace shoes to take the pressure off this part of your foot:

I use corkscrew elastic laces and do the alternate hole type lace pattern. It really takes the pressure off my instep and my numbness and pain went down considerably. The laces give and stretch and do not pinch the foot instead.
I don't know how anyone can diagnose CMT with a blood test that is not a DNA one. So don't assume you have this, quite yet.
You can do many many things for your feet at this time yourself.
The shoe lacing trick is only one of the things you can do.
Good luck.
