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.

Karen, hi, im so surprized that we would have both components through the duration of rsd- that it can be so extreme in the spectrums. I was incorrect, I thought that whether hot or cold, we both suffered from vacoconstrition. I thought it just changed with the life cycle of rsd. I went through the heat in the early stages. Now with the cold, I still have excessive sweating its a huge problem requiring potassium replacment reguarly, I really try to watch it as nothing burns more than an IV of potassium. do we both have the blood pooling, I understand that our nerve cells literally leek blood. I have had lesions that look like blood blisters, so so painful. If i knew how to post pictures i would show you. Dr. S has told me that our edema is different, its in the nerve cells or rather its the nerve cells holding the fluid and leaking the fluid. the blood goes down to my extremeties but does not return,as my body considers them as lost cause. it still seems so odd to me that the disorder is on both ends of the spectrum vasoconstriction and vasodilation..and I agree we may have them both at the same time in different parts of our body. thank you for you post, hoping you have a good day, cz
