I'd just like to say that I agree with en bloc. If you wish to pursue and perhaps discover the cause of your Neuropathic pain, you should, by all means. And, as my Neurologist told me, "if we discovered the cause of your neuropathy, that doesn't mean that your treatment for your pain would not be the same". I know I have been at wit's end trying to find if Vitamins make a difference, and finding shoes for comfort is challenging. It may all come down to how much frustration you are willing to go thru, without accepting the fact that the drugs may help make TODAY a bit less frustrating while you are looking for something that may continue to be elusive. I went a year and a half, suffering while turning down the drugs. Today, I do what I need to do to keep on going.
