My PN started as itching between several toes, that turned to burning within about two months. Then about a month later, the burning progressed to extreme burning, hypersensitivity to touch, numb areas, frequent "electric" feeling shocks in the joints, and intense throbbing pain between the metatarsal heads of both feet. Walking was hobbling agony for years, and I couldn't sleep at night for the pain. From your description, a lot of this must sound familiar to you.

A neurologist could give you a diagnosis.
