Kim, I really hope that migraine is subsiding now...ten days is too long for a migraine, for all sorts of reasons
I echo what the others have said - tell your GP and pain doc as soon as you can so that they can factor it in to your meds and your CRPS symptoms. It might be connected, it might not, but they need to know about something like this because it's that off-the-scale kind of thing that CRPS seems to provoke.
For what it's worth, I find every kind of ailment is worse with CRPS, and whenever I'm feeling ill in some way, the CRPS burning symptoms are worse, and can seem to crop up in the area that's suffering. It's like the crips visits anywhere poorly to join in the party for a while....not cool. As whatever it is gets better, the crips skulks off again. My actual spread has just happened totally unconnected to anything else, with no rhyme or reason that I can fathom.
Take care of yourself, and try all the soothing things you can....I hope something works very soon.
