My hands and feet have alway felt cold to me (some coolness but not much to other people's touch, not like Reynaulds) even before the RSD. My hand did start to turn a bluish/purple but now has a red area on it. My legs are always mottled & my knees get purple. But, sometimes my feet will get "hot flashes". Weird. I too, almost always have on socks & slippers. Wish I could wear those cute shoes I see others wearing.
