RSD is really a weird disease. My wife (she has RSD) has the opposite effect. Winter she can tolerate, heat she can't. She keeps the thermostat down to 65-. She's sweats alot and just shuts the vents off. Now, like clockwork if the barometer drops that's big trouble for her. We have a gizmo full of red fluid that travels up a class tube when the barometer drops. I'll watch it fill and observe Suzy's increasing pain every single time. She places it near me so that I will know visually when things wont be so good for her. Very sad.
