I get terrible hotflashes a lot of the time. Last week it was SO bad that I took my temp, just to make sure I didn't have the flu or something. My temp was 96 degrees. I'm usually subnormal and I remember reading on this forum others who have subnormal temps. My hands and feet are usually freezing, at least in the winter time. When they get this cold I can barely move them. I get tingly sensations in my hands alot, too.
So, I guess you're not alone with this problem.
Take care,
