hi, i took a yellow liquid medicine as an expectorant to help me cough up mucus. its also a very strong pain killer and relaxant, it was my mothers for when she got out of surgery for her back. she gave it to me cause she said it would help with the mucus. it had a sweet flavor to it. it made me extremely dizzy and fuzzy when i took it, ive felt that way all day, have had nightmares when i try to sleep, feel numb. now im feeling very very hot, but when you touch me i dont have a fever. but i am extremely hot. ive been taking showers every few minutes to cool down. whats wrong with me, and what do i do?
