I have never checked my temperature, but I have MAD heat flashes where my body just goes bazurk hot where I have to turn fans on and air conditioner on freezing for hours, literally sit in the freezer and am still burning up. Everyone around me will be dressed in layers with layers of blankets and are freezing as I am half naked burning up hot.... so I wonder if I am "fevering" as well?? This goes on for hours sometimes days, I sometimes get a few hours of relief and it comes right back. It happens mostly when I am really flared up. Do you notice it when you are in higher amounts of pain? even though it really seems like all the time... sigh.... hang in there!
