Littlemary, I'm so sorry you are going through this. Like you I have no diagnosis and am waiting and in limbo so I truly know how frustrating it is to be in pain with no real "reason" (not to say it's not valid or even not there, I know it is). This forum has lots of friendly people and they are wonderful and supportive.
It's so frustrating to get told oh we thing it is x, and then the next doctor tell you no it isn't and it might be y illness instead. Going to the Rheumatologist is a good idea I know I've moaned and groaned about going to a new doctor and had negative thoughts (such as: they're just gonna say it's whatever, or that it's not this, or that they can't help me why bother?).
I hope that the Rheumatologist can help you, and I'm so sorry they think it's CRPS, I too am bouncing around on that possibility with no confirmation. Take care of yourself and remember that it's okay to be frustrated, a little angry, or emotional. Take it one day at a time and keep positive.
