So I'm very new to this. Last week my second blood tests show that I have an overactive thyroid... my next tests are in 3 months to see if it calms down. I was told I may have problems with my body temp... well today I've been really hot and can't cool down. Not sweating... just hot. Anybody else feel like this and what can I do to cool down ? There must be something. I'm a 44 year old male btw.
