I've had neuropathy for over 30 years but am fortunate that I only have some numbness and no pain. I've never been worried about amputation of my feet. My younger sister who has passed away some years ago had diabetes along with other complications and was close to having one of her feet amputated but it never got that bad.

From your previous posts it sounds like you have been dealing with a lot of pain in your legs and feet and have tried a lot of different treatments. Have you looked into any of the complementary or alternative treatments on the Foundation for Peripheral Neuropathy website? - https://www.foundationforpn.org/wp-content/uploads/2020/08/Complementary-and-Alternative-Treatments-Revised-2020-final.-1.pdf
