Jessica,
First of all, Welcome, you have come to the right place!

The people here are very knowledgeable and caring!!! I'm pretty new myself, and have learned most of what I know about it from here. I do know that you will get the temp difference with the burning, which to me is the most crazy. My arm will feel like it is on fire but feels like ice to someone else.
CRPS is a very emotionally straining issue to deal with, find a good support system, that is important! Again, this forum is a great place for that also
Sending healing love and

Dawn
