That's my DX also - polyneuropathy - idopathic. mine started with numbness in the thighs which is just weird. Then the tingling and pain (both stabbing and burning) and then the hypersensitivity that hurts when I do things like wear pants was added to that. I get stabbing pin pricks in my arms and burning in my lower back and sometimes my feet go numb. Meds aren't working to well, some days are better than others. My neurologist did admit that treating neuropathy is more of an art then a science. She referred me to the Hopkins pain treatment center as I'm only an 1 1/2 hours from Baltimore. Everyone seems to progress differently with this condition. I guess we're all unique and neurology really isn't understood that well yet.
