Welcome to Neuro Talk. I am glad you found this site. There are alot of people who experience this kind. PN, RSD, CPRS all of these neurological problems can take a while to diaganos. I would definately go see another neruologist for a second opinion. In some cases the sooner you find out what is going on, the better the outcome. I am sorry you are dealing with this kind of pain. I have NP in my left foot up my calf. No pleasant at all. I hope you can get the help you need. There is a search bar up at the top of the page, that can get you to any forum you want to talk to. There are seperate forums for all three of these issues, that will offer you more information. Again a warm welcome to you, I hope you can get some help. ginnie
