Could you tell us what you are taking? Gabapentin often has to be combined with an opiate to relieve severe pain, that's if the Gabapentin is helping t all, it often doesn't. It does help me, my legs and feet buzz if I miss a dose, but it doesn't touch the deep "bone" pain. (it feels like the bones are being crushed).

My PN is hereditary, but symptoms are similar enough. Lots of idiopathic cases turn out to be hereditary if other causes, diabetes, toxic meds, autonomic, are ruled out.
