So, your PN was not ideopathic - it was related to diabetes and hypthyroidism.

I don't have diabetes and my hypothyroidism is under control (for nearly 30 years) and my B12 levels are normal.

That is an impressive list of supplements. I don't think doctors know much about supplements. Or care. I think for each of us - regardless of the medical problem/symptoms - it's doing research and trial and error with the various supplements.

I am glad you don't have symptoms that often and have found what works (and what to avoid) for you. Plus that's great that this approach has worked for other members of your family.
