Mr.Pete, With my Rsd it really comes down to what the weather is up to here in Wisconsin. You could not live in a worse place and have RSD! The winter's here are brutul also the other season's can be the same way. I once had a test that had something to do with monitoring my sweat glands. The DR's found out at least with me that I had stopped producing sweat all the way from my arms to my feet. I can go out into the sun even when it is in the high 80's here. However I cannot stand to be touched it hurts so much So I think you can put me on your list for Cold RSD! Thanks so much for being one of the caring ones! Take Care! Breezy55 Oh one last thing it is so hard to have clothes touch my body when I am having a major flair. Or to try to even have my skin to come into contact with my sheet's at night takes forever.Night time for many of us can be the worse time to think about. Just to know if you are going to sleep or not?
