I was diagnosed with chronic Sensorimotor Axonal Polyneuropathy three years ago at Weill Cornell. My three daughters and I were invited to undergo a Whole Exome Sequencing test because we have a family history of PN going back five (or more) generations. The neurologist at Cornell gave us EMG and needle EMGs and that’s how I was diagnosed with the Sensorimotor Axonal Polyneuropathy. The genetic test came back and I have CMT2 and CMT4B. Daughter 1 has no CMT mutations. Daughter 2 has the CMT2 mutation. Daughter 3 has both the CMT2 and CMT4B mutations. No cure for these suckers. My feet and fingers tingle all day and I have reduced sensation in my toes, feet and fingers. Still driving but I know my driving days will end sooner than later. I tried Gabapentin and Lyrica but turns out I had bad reactions to those pain meds. Good luck.
