I was just dx'd with painful polyneuropathy...after years of having peripheral neuropathy or diabetic neuropathy depending on which kind of dr you talk to...now with peripheral or diabetic it is usually in the lower parts of extremities...numbness and burning in hands feet or midway up leg. Polyneuropathy deals with the small nerves and makes pain more acute as your nerves misfire and misread and make it 'painful'...it can occur all over as far as i know and my neuro did a safety pin test (he bent it str8 and poked me HARD) and I didnt feel it anywhere as pain, just a finger poke type, but the small par tof my back and he said i have severe nerve damage...he is hoping cymbalta will help and i am hoping for pain relief...this is the little info that I have...hope it helps some!! ~ Melanie
