I wake up during the night as my body's overheating. It makes me feel sick and I have how I would describe as pin prick pains zapping different parts of my body. It also happens in my head. My body feels like a fire ball inside. I suffer with inflammation with having rhematiod arthritus and sjorgrens. Wondering if anyone else has experienced this...I am waiting to see a neurologist as I have explained this to my rheumy doctor....???
