Currently sitting in the ER waiting room, three hours in. My mother has been to two doctors in two days, this is our second ER visit in two days, they keep giving us mismatched information. "I'll get her a popsicle in a bit, we don't want any free fluid". It's been an hour so I ask the receptionist about it, a second nurse says something about a CAT scan so she can't have any liquids. So my mother hasn't had any fluid since we've been here at 2am this morning. Both wings are full, they are in no way prepared for what's going on, tons of people just being triaged and shoved back into the waiting room.
