Diabetic neuropathy is a disease of the nerves thought to be caused problems of the small blood vessels that feed the nerves. Numbness, tingling, and the burning sensation you describe are common complaints in diabetic neuropathy. Some medications that have been shown to be helpful are not typical pain medications at all, but are generally used as antidepressants (such as amitriptyline) and anti-seizure medications (gabapentin). Speak with your doctor to find out if any of these may be right for you.
