Hi @jewles63, I just have the numbness with my idiopathic small fiber PN and it can be a little depressing not knowing the cause behind the neuropathy. I was diagnosed through physical exam along with nerve conduction tests which weren't normal. They guessed mine may be hereditary and I can go along with that since I have a younger sister that has similar symptoms and another younger sister who passed away that had neuropathy due to diabetes. I also have some cousins with neuropathy. I do think cellular nutrition plays a part after reading Dr Terry Wahls story about her struggle with MS - https://terrywahls.com/about/about-terry-wahls/

The diagnosis may not be the answer we want but it can provide some incentive for us to learn as much as we can about our condition so that we can make better choices and ask better questions of our doctors. Hopefully along the way of our path of learning more about our condition we can run across something that helps us.

What amazes me is the how many health conditions can look similar and make diagnosis more important and difficult at the same time. Here's some information from 2015 on the topic.
