@onlinescoop - I had the neuropathy symptoms 20+ years before finally deciding to get a diagnosis, mainly because the numbness was progressing up my legs. I waited because every PCP I discussed it with told me it was probably nerve damage and they could do some tests to determine if that's the cause but when I asked, if it is nerve damage what can you do to treat it, the answer was always nothing. So I kept waiting to see a neurologist until I wanted answers and I got them. Unfortunately for me, it was there is no treatment for the numbness. The diagnosis was done through nerve conduction tests and a physical examination by the neurologist. I have had several genetic tests but neither showed causes that have a connection with neuropathy. I have often thought of having a skin biopsy test to see if it could confirm whether or not my neuropathy is getting worse but decided it's not going to change or offer any new treatments for me so why have it done.
