This is very odd to hear for me because I'm totally different. When my body goes in temp fits (that's what I call them) I get freezing cold chills. I even have gone as far as sitting in my car with the heat on and fan blasting while it's 90 degrees outside. All the while only my RSD hand and foot will feel ice cold and the rest of me is warm.
I also lay in bed at times covered up with blankets and be shaking from being cold while the a/c is on in the house because it's so hot out.
Whether it be hot or cold the temp fits are real and such an aggravation to deal with. I guess only we understand them best because they're happening to us...
