No, my small fiber neuropathy is idiopathic (no known cause). When my feet were really bad and burning/tingling/pins and needles pretty regularly, I started taking 600 mg of alpha Lipoic acid. It started working after a month and my symptoms started to improve. I also noticed my feet were worse in warmer weather and when walking (not sure if due to swelling/inflammation aggravating the nerves more). Compression socks and cooling my feet helped and I also used nerve pain creams.
