I have Graves Disease, and even though my labs say I'm fine, I do not feel fine. I constantly fluctuate from being too hot to too cold. It's crazy. I sweat like crazy in bed, then I freeze, but as soon as I put covers on, I'm hot. There's no real rhyme or reason. I'm hoping it goes away eventually. Good luck to you!
My example of hot and cold is I will be sweating under my arms and my feet and hands will be cold. Also, at night I will wake myself up with jerking cold. Almost like spasms but Iím freezing. The night thing happens fully clothed with socks on. I have not yet been to the endocrinologist so I can not tell you what causes this.
I have graves and was recently dx with adrenal fatigue by an alt med dr going by symptoms alone. A couple of the symptoms for the adrenal fatigue is being cold and lower bp. This fit for me. I was a cold person with chillin' bp and hyperT labs.
From all the stories here it could be a possibility that other hormones(reproductive or adrenal) and your thyroid are battling over your body temperature. Kind of a tug of war.
