Ok, now you got MY interest. B-12 and folic acid patches? If I humbly ask, how did you come across this information? I also have neuropathy in my feet and if this will help, I’m gonna check it out.
A nurse told me about it years ago and I’ve been using them ever since. I get them from Ganesha on ebay. Best price, good service. Never had any problems. Not only does the patch help (eliminate, in my case) the neuropathy, but you’ll find yourself a bit peppier and your mood happier.
