Hi Andrea! So sorry you are having to deal with CRPS and all its lovliness! I think all of us suffering from this have shared these symptoms/reactions/feelings...whatever you want to call them. I am struggling with some of that myself right now. RSD/CRPS affects the limbic system of the brain. See the link below for some explanation:

There is also more great info on that website www.rsdhope.org.

All the best,
Nanc
