This is the second time in a year this has happened to me. I wake up feeling like I am in a solid block of ice and can t get warm no matter what. I am shaking so bad my teeth hurt from chattering and my temp when I check it is always around 102.07 or this last time it was 104.02. Last time I went by ambulance to the ER. I forgot what they told me what it was but it lasted about 12 hrs and I was fine. I just woke up tonight feeling pretty much the same way just not as bad.
