Not sure, they have diagnosed it so far just as hereditary sensory and autonomic neuropathy, have mentioned cmt, but I can not afford the testing for it. The new neurologist wants to do another emg test, and a nerve biopsy. He also mentioned spinal tap, but I am not doing that unless it is a 100% must. The nerve test is bad enough. I am concerned about the biopsy because in reading the forums it has brought more pain then people have had prior to having it done, so it worries me.
