Hi Mike, I don't know what will work for you but I can tell you a little about my journey with neuropathy. Ive had for 8 years; although now it is mostly managed. I have never found the cause. I have small/single fiber neuropathy that was diagnosed by my foot doctor. I also went to a neurologist for further testing where I didn't find out anything more. In the last 3 years, I have researched and changed my diet as I read that carbs and sugar make it worse. I have also forced myself to walk a lot more even when my feet hurt. I joined a walking meetup group which helped with accountability. I had surgery for a separate issue which then put me on a low fat diet. In the process I lost 50 pounds. Walking and weight loss were the big treatments for me. I never had diabetes or pre diabetes. Only thing maybe is that I had thyroid cancer 20 years ago so could be cumulative effects of medication or radiation treatment that i had. It could also be the additives from all the bad food choices I used to make. Now I only eat whole foods, vegetables, chicken. I find if I become a couch potato or get the flu and am inactive for days/weeks the neuropathy comes back. It is good to find the underlying cause but even if you don't find it (many of us don't), there are other things you can do to get relief. I wish you the best and hope you get some relief.
