Sorry you are in so much pain. I too have PN or RSD in my left foot and ankle. I was prescribed a lotion that really does help. an orthopedic surgeon first suggested it, then my pain specialist did. There are 5 compounds in it. This releaves alot of the pain, not all. KETAMINE/CLONID./GABAP./IMIPR./MEFEN ACID/ TETRACAINE (5) 10/O.2.6/3/3/2% CREAM. It is worth a try. Medicare part D will not cover it however; is very lousy to do. I would rather rub in this lotion than take a narcotic that is covered. I am not sure why medicare part D will not cover this compound and I have written a letter or two. My doctor is going to bat for me too. Ask your physician about it. ginnie
