Our patient in the general medicine outpatient clinic is Margo, a 49-year-old woman who has come in with her husband with a chief complaint of “I’ve got this cough again.” Margo says that she gets a cough frequently, a bad cough that lingers for weeks, and she keeps seeing doctors, and it gets better, and then it comes back. She thinks this time it’s her allergies, because it’s the fall, and she always gets this cough in the fall.
