I have been feeling very cold for some time (2 or 3 weeks), I am 41 yrs female (10.5st, 5ft 9). I have had a bit of a cold on and off recently but have never experienced such coldness (and it is not followed by hot flushes, definitely no temperature 37 yesterday). I am even sitting in a hot office, full blast heating and still feeling cold and shivery if I go outside my door. If I cover myself with warm clothing, I do warm up but it takes a while.
