@magnum52 - I was diagnosed with idiopathic small fiber peripheral neuropathy at the Rochester Mayo Clinic but found no real help other than the diagnosis but that was because my symptoms were numbness only and there is nothing they can do for numbness. I wasn't aware of any specific research but did find some peripheral neuropathy clinical trials listed here for Mayo Clinic Rochester - https://www.mayo.edu/research/clinical-trials/diseases-conditions/peripheral-neuropathy
