My father has diabetic neuropathy and his Home Health agency, I think it was Amedisis, treated him with Anodyne. After a couple weeks, he told me pain and tingling started to fade. By the end of the month, he could go to the grocery store by himself and not have to worry about his feet hurting too much to walk. It's really changed his life. He hardly ever takes anything for pain, except for his back, and he said he can sleep better and through the night.
I'm surprised that I haven't really seen Anodyne mentioned on this forum. I can't imagine how horrible it is to suffer through something like this and not have any hope. It really helped my father, and I hope it helps you, too!
