I'm not familiar with CRPS, so can't really separate it from Lupus symptoms for you. Fever & fatgiue can occur with so many things, and so can a red face. I don't know that I'd put lupus at the top of my suspicion list - best to let the Drs decide.
My suggestion would be to report everything you've told us to your GP, and get a referral to a rheumotolgist for a workup. A rheumy is the Dr who diagnoses & treats diseases like Lupus -- many GP's say things about
lupus but they don't really know much about
Check out the Lupus Resources thread for tips on what to tell your Dr and to see how lupus is diagnosed.
Hope you feel better soon,
