I have Chronic Sensorimotor Axonal PN, CMT2, and CMT4B. My symptoms started when I was about 60. Some numbness in my feet, hands and calfs. Currently, (age 79) I have almost no sensation below my hips and elbows. Walking is difficult and my balance is awful. My current EMG test results indicate “no response” so I don't feel the electrical stimulation. Years ago I did and the electrical blasts were painful and I was uncomfortable but the test is over in about 10 minutes. CMT is hereditary so my 4 children and I had genetic testing for these PNs. All 4 of my children inherited the gene mutations for CMT2. My youngest daughter also inherited the mutation for CMT4B. Bummer. That makes 8 generations in our family that we know of. The gene mutations come down on the X chromosome so thanks mom, grandma and all the great grandmas on my mothers side. Seriously though, CMT is simply annoying. The Sensory Motor Axonal PN disorder is the real problem. My kids did not inherit the gene mutations for that sucker. Thank God for that.
