Hello @intlguyct, Welcome to Connect. I wished I had some good answers for you. I know it's a struggle dealing with neuropathy whether you know the cause or not and it can be painful and scary. I also have idiopathic neuropathy but fortunate for me I only have the numbness and some minor tingling. The reality is that knowing the cause may or may not be helpful in treating the symptoms. My best advice I have to offer is to learn as much as you can about your condition and what treatment options are available that might provide some relief. Two of the best sites to learn more that have helped me are:
--- Foundation for Peripheral Neuropathy: https://www.foundationforpn.org/living-well/
--- Neuropathy Commons: https://neuropathycommons.org/neuropathy/neuropathy-overview.

I shared my neuropathy journey in another discussion here - Member Neuropathy Journey Stories: What's Yours?: https://connect.mayoclinic.org/comment/310341/.

You mentioned that the gabapentin and pregabalin didn't work. Did your neurologist offer any other treatments or suggestions to help with the pain?
