Hello @dutchman09, welcome to Connect. I have idiopathic small fiber peripheral neuropathy in both feet and slightly above the ankles. I'm fortunate in that I only have numbness and some tingling as symptoms. I don't have any pain with it. In looking for "fixes" for my neuropathy I tried a lot of topicals and a few devices with little success. What I did learn is that there are a lot of companies and others making a lot of money off of people with neuropathy symptoms. I purchased a Zopec DT-1200 Electrotherapy system which claimed it helped neuropathy and had lots of good testimonials but it didn't work for me. I have heard of the Rebuilder but think it's just another one of those things (IMHO). I did find an article talking about it:

I try to do research on any new treatments for myself before making any decisions. Here are a few of the sites I use:

NIH's National Center for Complementary and Integrative Health (NCCIH) which offers guidance about integrative health and how to evaluate it.

I'm also a big believer in not taking statins because I have neuropathy and statins can cause neuropathy.

@dutchman09, do you have any other symptoms of neuropathy other than your left foot? Mine did start in the toes but on both feet.
