See a neurologist who knows something about small fiber Neuropathy. It’s a simple test consisting of small skin biopsies. The EMG won’t properly diagnose SNF. I’ve been there. The EMG is painful!!!!! It proved nothing. But that was me. It took the 3rd neurologist to even consider trying the skin biopsy. Unfortunately for me, it proved positive. There are many types of peripheral neuropathy. Find a neurologist with some SNF background. Good luck.
