Hi Debi.
As far as EMG/nerve study since they're not too bad comparing could be interesting. Of course it won't show SFN. Refresh my memory, did you ever have a punch biopsy?
As far as going to see a neurosurgeon, since their last name is "surgeon," that is what they are trained to do and usually what they recommend. I have to say not all, but most are very pro surgery. SO, with that in mind, I would bring someone with you who would keep you from signing up in the office that day for any surgery. Kinda like when you go to buy a car. The good thing would be you will have more data to consider and in my mind more data is not a bad thing.
I hope this helps.
