Hi! I hope you get some answers soon. But with respect to your questions about stress: Stress can make anything feel worse -- that doesn't mean it caused it. Be careful not to fall into the "blame the patient" pattern.

That said, my whatever-it-is gives me Raynaud's symptoms in my hands and feet, but not from cold. It is usually provoked by too much exercise -- or getting upset. Like, if I cry, my fingers turn blue. How's that for weird? Meds help, but so does self-hypnosis and other relaxation techniques, particularly if it was set off by upset rather than exercise.

I hope this helps. In any event, keep talking to people, and try any mode of treatment that seems plausible and isn't dangerous. Just do it one at a time, so you can tell what works. And keep a journal to document symptoms; that's very helpful in diagnosing
