Glad to help you with understanding the difference. I hadn't seen Marleen's post or Sherri's before I post it. lol Those who start cold stay cold, those who start hot may, like you did, turn cold eventually. That "used to be" the criteria for rsd. Skin was hot first and cold later, which isn't true for everyone and I found most people have cold rsd and hot rsd is a minority. I'd have to dig up the stats on my survey again for the %'s.

Sweating, blood pressure problems and such are all due to the rsd wreaking havoc with both voluntary and involuntary systems. We can't regulate our body temperature anymore and get cold or hot when we shouldn't be. I only deal with some sweating at night that is mild but get worse at "that" time of the month. lol I think part of the reason for my lack of sweating as some do is because I'm very underweight now. I know it's hormones making the sweating worse at night near my period. Potassium burns you, seriously? Wow, I've never heard anyone who experienced that...interesting.

Maybe not so much blood pooling...it's the lack of blood flow that causes skin color change for me, but I think it's the excess blood flow, blood pooling in hot rsd though. I have blood blisters, known as petechial hemorrhages, all over my body, have since the beginning that turn into lesions. Even tiny ones take forever to heal. I thought I read somewhere what causes it but can't remember where or when! LOL
