mg neck prob - Well I have had symptoms that may suggest a small fiber neuropathy. Originally a neuro at OSU thought I had post viral large fiber neuropathy because of abnormal and then normal emgs within 2 months of eachother. But now I have been having symptoms of small fiber and I had a slightly abnormal QSART test this past summer. I dont know if this is what I have because I seem to have good and bad days. My symptoms include tingling, sticking pains, burning in my toes (especially when cold) and seem to be heat and exercise induced (is this normal?). How long did it take for you to get an apt and then have the sample analyzed? thanks so much!
