Welcome @cboydb, Your neuropathy journey sounds eerily similar to mine that I posted at the beginning of the discussion here - https://connect.mayoclinic.org/comment/310341/ and is what initially brought me to Mayo Clinic Connect in 2016. I also have the numbness and some tingling but no pain other than that related to old age and degenerative arthritis being an almost 82 year old guy. I've also been in the prediabetes category most of my adult life but only started focusing on getting my weight down and working on eating healthier after searching for ways to slow or possibly reverse my neuropathy. I do feel that I have slowed down or possibly stopped the progression but I continue to look for other ways to reduce the numbness. I still have it but it hasn't gotten any worse since 2016 which is a win for me.

I do think it's great that you already are working on fixing the prediabetic condition. I think there may be a connection to that after I started looking more into a reason for my diagnosis being idiopathic - small fiber peripheral neuropathy. Anything you can do to get out of the metabolic syndrome category is a win. Here's some information on how it is connected with neuropathy - The Metabolic Syndrome and Neuropathy: Therapeutic Challenges and Opportunities: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3881591/.
