Hello. I am undergoing testing for small fiber neuropathy and am wondering if anyone has had a similar experience. I have had several evoked potentials (EVPs) done that have had abnormalities. In the beginning both my legs and eyes showed delays which is common with people with MS. MRI was clear however I had a B12 defficiency. The last 2 years I have suffered with burning sensation all over my body and testing began again.Most recently the evoked potenials showed delays in legs only, the right more so than the left. They did and EMG and although the EMG results were normal, the left leg was in excruciating pain each time they "zapped" it, but the right side I could hardly feel at all. It. Is amzing to me that my legs would feel so completely different and yet the results would be normal. Next step they are doing skin biopsy. Has anyone had these types of sensations during EMG? You would think I would have the same feeling in both legs if it was normal. Also has anyone had abnormal EVPs that has been dx'd with SFN? Thanks!
