at my worst i was had both diahrrea and constipation off and on. The weird thing.... although ive never been a big sweater, one of my symptoms was lack of prespiration. I get verrrrrrrrrrrrrrrry hot, even when its not that hot and no matter how hot it is or if im able to exercise (which i dont have energy for at this time), i dont sweat! I just get red in the face..and swollen. i hate it. i feel like my body is not getting rid of toxins bcause of this. I checked my thyroid and doc says its fine. Although my T4 is slightly low, but the main test is fine.
