Check out my forum concerning CMT at the top of the page under "PN Tips, Resources, Supplements and Other Treatments". There are many many types of CMT. Symptoms of CMT can become evident when you are young, old, or in-between. Or symptoms might not be that evident.

CMT has been and still can be misdiagnosed as something else. The fact that your Grandmother has PN and cannot feel anything from her knees down is interesting. There are many types of PN out there. Does anyone else in your family have anything similar? Hopefully you will get an answer soon. An expert neurologist who knows CMT might be in order in the initial diagnosis if indeed CMT is suspected.

February is a long time to have to wait. Perhaps you could find another doctor.
