I did say no right now. They have done lots of blood work, the MRI showed nothing, the emg according to the doctor that did it showed "excessive nerve damage that is dissipated throughout my body, which is extremely rare and not good for my age." The 1st neuro said it probably wasn't cmt because I would be worse than what I am now. The newer neurologist said he does see some signs such as arches, and slight hammer toes on one foot but wants to rule out other things first. He said he wants to rule out any other possible underlying conditions. He also said I have had this for a long time. What other tests can they do to rule things out without spinal tap?
