Your best bet is to go on the Internet & look up Small Fiber Neuropathy and also the Sanexas .
I have Peripheral neuropathy & I am under the care of a place in Peoria that uses the Sanexas & they use shots with their treatments. I am very ok with the shots, as they are only injectable blends of vits & mineral.
I do not want to take drugs or do surgery. I will complete the treatments & later on in life, if it starts to come back, I would do follow up treatments.
So, please research. There is a lot of information out there & also lots of info that says, "you have to live with it."
NOT ME I got to feel the "fur" on the sole of my slipper the other day & it was great. I haven't had that feeling for years (foot numb).
