I have the cold feelings, not the flames. I also don't get swelling (unless I've really overdone it), but I do get blotchy purple skin. For me it's like when you've been out in the cold way too long, the pain like frostbite is next. My feet can be sweating and they still feel like that (and they'd only sweat because I keep trying to warm them up to combat that feeling). Most of the time they're cold to the touch. So yes, it sounds like our symptoms are similar.
