I'm new to this forum so let me introduce myself, I am a 48 y/o female from Arizona. My question is: I have a problem with being cold for several years. Now I am having problems being cold then hot then cold. I first thought being hot was hot flashes, but that has been ruled out. Does anyone have symptoms like these? I get tired of putting a sweater on and off all day long, and covers on and off all night. Could this be thyroid?
