Alisha,
All I can go by is my own experiences.
My RSD (or CPSD) stared in my left wrist and has spread up my arm, shoulder, neck, left side of my face and now it's turning north and also my left leg.
The symptoms were different each time it spread but the pain and sensitivity was pretty much the same. The more I read the more I realize that there's really no set pattern for this monster. We just end up with close to the same painful fire and ice.
So sorry to hear of your battle with this monster but at least in here you're not alone...
