Now I do not know if this is true or not, but my Neurologist said that opiods do not work for Neuropathy. I too, have foot neuropathy. I would say it was utterly intractable. I finally had Calmare/Scrambler therapy, and it has provided some relief. But the pain of neuropathy is excruciating. Unimaginable. I will look at everything you sent. I am always trying to learn and research what can be done. You might also want to try a product called Kratom. It is from a plant. It is for relaxing and pain, although no claims are made about pain on the site I get it from. Look up Happy Hippo, and try some Kratom. Try a slow strain of their product. This is the type that helps with pain and relaxation. Happy Hippo is a very reputable company. Good luck with your pain. Lori Renee
