I was diagnosed with hyperthyroidism 7 months ago. for 6 months I have had persistent nausea. my doc say stress.. I m not stressed 24 7. the past two days my body cant seem to be satisfied... I get really cold so I turn on the heat, seem like after 4 minutes of heat I m too hot, I feel moist but not sweating. I latterly alternante my heat and air every 10 minutes. this is through out the the day. at night I get extremely thirsty, the back of my tongue feels like its dry, but when I feel it its moist. it also feel enlarged in the back, when I look, it looks normal. got any advice. will see my wonderful doc next week...
