I am 17 years old, female, with recently diagnosed hypothyroidism . I didnt get a very good nights sleep last night so at 5pm this evening I fell asleep in bed and woke up at 8:30pm, feeling really hot and flushed, and feverish, took my temperature and its 36.6 celsius so not raised at all, in fact, lowered for me because my temp is usually 37. Do i have some sort of fever starting?
