Not to mention that "take two aspirin and let me know if it doesn't get better" is probably literally the best way to handle a case that could be something serious, but there's no way to feasibly discern yet whether it is something serious. Obviously the specifics of this type of scenario can change over time, e.g. if MRIs or CT scans became very cheap and easy to administer, I suspect they would become part of these routine exams.
