Last night I awoke around midnight shivering and freezing cold. My window was open and my fan was on, but the overnight low was just 62 degrees - and considering I had two blankets and a sleeping bag on me, I don't think it was because I was cold. Also, I awoke three times in the night having to go to the bathroom, to go pee. Then, when I woke up, my whole body was sore and I didn't want to move. Also, I had a pounding headache and feel warm. Is this just a virus or a cold or something? I'm not too worried about it, but I would like to know what it is without having to go to the doctors. Thanks.
