My feet are always frozen and it was that way prior to SFN symptoms. Strangely enough, I tend not to wear shoes or socks every chance I get because it helps my feet not burn as much.

My hands are always cold too. I get purple finger tips from cold exposure. This started 2 months before my symptoms came on. I have no burning in my hands, but sometimes it feels like they are swelling. My hands look like they should be as big as marshmallows, but they are truly not swollen at all.
