Liza Jane, I have a question. I was diagnosed with idiopathic, small fiber, painful sensory neuropathy 8 years ago. I have not developed any weakness, but without medication my pain approaches a 10. Why do you say that if it is sensory it must be CMT? My neurologist never mentioned it to me. I thought CMT was alway hereditary? Is this a new thought on sensory neuropathy? I would appreciate any information you could give me. Thanks.
