Hi Louise, first let me wish you a pain free life so you'd be free from suffering. I've had PN for over 10 years and have tried almost everything and still searching for the solution to my inflammation flare-ups during the day. If I understand correctly, you started with a pain doctor and have yet to go to a neurologist. Isn't that backwards? The first step in getting better from anything is to know exactly what you have. Go see a neurologist and a nerve specialist, if necessary. I say this because my PN encompasses my entire foot (both feet). The various pains (coldness, burning, nerve "shocks", cramping , etc.) are coming from within my feet, not bottom or top. Maybe you don't have neuropathy. In any case, get the info first and then attack your pain with everything. Wishing you the best of luck!!!
