It seems that most everyone here is posting about diabetes or pre-diabetes. I have had my idiopathic small fiber peripher neuropathy for 10 yrs. after"per doctors" post infectious " I had explosive diarrhea several times, ached all over, neck hurt, had a jab of pain up inside sinuses way up high inside nose, waves and waves of pricks sensations over entire body head to toe. Sinuses secretions have thickened - abnormal sensations all over face and body. Nothing helps. Any advise?? I had a spinal tap one year after I first got sick and the CSF showed WBC at 9 and doctors like it below 5. Now why after one yr. at the time wouldn't they treat it if WBC in CSF was elevated at 9?? One doctor said I have a brain lesion right on the part of the brain that controls the autonomic nervous system. I saw 5-6 neurologists and only one noticed it. Anything for someone that is not a diabetic??
