Neuropathy is such a common and painful complication of diabetes that I watch out for all research reports about it, no matter now preliminary. Half of all of us who have diabetes have some form of neuropathy.
Until recently most treatments for diabetic neuropathy have been painkillers that helped some people but not others. Even if they helped control the pain, they did nothing to reverse the neuropathy. My web page on “Diabetic Neuropathy” describes many of these treatments.
