If you're near a drug store or grocery store with those free blood pressure machines, I'd suggest checking your blood pressure. RSD sometimes causes low blood pressure ("hypotension") which in turn causes random fainting. Which causes injury. Are any of the meds you are on specifically for treating blood pressure? Or are any of the meds' known side effects related to blood pressure? These are some things that you could check out on your own while you are waiting (endlessly!) to be seen by a doctor.
