The link above for the Foundation for Peripheral Neuropathy's Living Well page has a link to a better explanation - https://www.foundationforpn.org/living-well/complementary-therapies/. Also, there is a link on the page that has a PDF list of all of the different treatments and supplements that people have found helpful - https://www.foundationforpn.org/wp-content/uploads/2020/08/Complementary-and-Alternative-Treatments-Revised-2020-final.-1.pdf.
