I have cold rsd too. Here's an explanation between the hot and cold. They aren't the same thing at all. One, cold, is vasoconstriction. Hot is vasodilation because there's too much blood flowing through the blood vessels, versus cold where there is a lack of blood flow.

Vasoconstriction reduces blood flow (area is usually cold, white or dusky in color), vasodilation iincreases blood flow (area is hot, red or excessively pink).

Here's a link that explains it as well,
Heat/Cold Adaptation. It says what the quote above says. "Red skin indicates vasodilation and the pooling of blood near the surface for release of heat."
Hope this helps clear it up. :-) Some people start off with hot rsd and it gradually changes to cold, but cold usually stays cold and sometimes people can have both at the same time.
Hugs,
Karen

In the begining my legs were red hot, as the stages advanced they went cold, but the underlying problem was always vascocontrition. So is it the same. sorry for my awful spelling. cz
