I might ring someone. I've been driving for 10 hours straight, so getting back in the car, with all 3 kids alone, is not the best idea with how tired I am. I know how that sounds, but this is the best I can do right now. An extra 12 or so hours is better than me falling asleep at the wheel on the way in to town, or back out in 4 or 5 hours when they get around to seeing her.
I'm going to look up the symptoms anyway. See what I can find out.
