I went to the ER with severe facial and sinus pain, to the point where I was screaming and could barely see out of my left eye. I waited 30 minutes for the doctor to come poke my face a few times, ask if it hurt, then proceed to write me a prescription that would later reveal to be the wrong kind of medicine. Then I see a bill for $500+. $500 for a doctor to poke me in the face and give me the wrong medicine....specifically the ER section.
