I've been sick with a cold since Thursday. Had to go to the ER (because the urgent care wasn't open til 9am and this was 6am) my sinuses were so full of pressure that my ear drum was swollen. So I got some sudafed and took a nap (my daughter was with my parents so I could focus on myself) now its just a normal annoying cold, but as of today I've had a horrible headache, dizziness, nausea (which is making me want to get a test cause I don't get nausea except for when I was pregnant), almost throwing up yesterday (but that was being car sick which has happened before, we went pumpkin picking) and today, my boobs have been tender/sore, and I'm just tired all the time....
