I do not believe that there is anything that will reverse the damage i.e. regenerate the nerves. However, at the suggestion of an internist who believed the PN to be idiopathic, I have been taking B-6, Folate and B-12 for years solely to hopefully prevent further damage to my nerves.
NB. I have not experienced pain just numbness.
I am considering adding B-1, or an equivalent, and possibly other supplements to enhance the effect of the above named supplements.
To improve balance I wear professionally created firm inserts (to address my congenital flat feet) and have finally found a pair of low profile hiking shoes that are comfortable, attractive and stabilizing. Together they have improved my balance and lessened the pain I have in one knee because of bone-on- bone. This has become my go-to pair of shoes for outdoor and indoor wear.
I also do balance exercises and never go bare foot.

@tedkaplysh Thats funny because I always go barefoot because shoes make my toes go to sleep. I take Alpha Lipoic Acid for my PN. I also am going thru a new treatment called Battlefield acupunture. it seems to help with the fogginess and some with the balance, but mostly (50%) better are my hands. they still go numb, but not near as often.
I have also found that finding a Dr. that has really studied PN, is like looking for a pin in a haystack. I've gone thru 3 so far. One told me to stop taking my COPD meds, the last one told me that I have carpel tunnel in both wrist is all.
