This is the website of Dr. John Hayes, a chiropractor in Massachusetts. He claims to treat neuropathy successfully. I'm sure this will depend on the cause of the PN. I have listened to many of his podcasts and mostly like what he has to say. This is my take on what he mainly does, but I could be wrong--Make sure the patient doesn't have a serious disease other than neuropathy, then do what he can with chiropractic care, and apply some program of diet and exercise to treat chemical imbalances in the body, such as metabolic syndrome, which he talks about a lot as a cause of many of the chronic diseases we see Americans suffering today.
I think the podcasts are pretty good, although he doesn't go into a lot of detail about any treatments. For the podcasts, see http://www.beatingneuropathy.com/
If you are not familiar with podcasts, they are basically like listening to talk radio. You can play them from the website listed above, from a smart phone, MP3 player, or if your vehicle has a USB port and can play MP3 files (which I understand most new vehicles do) then you can play them while you drive (which is what I do). Each of his podcasts is about 30 minutes long.
