A medical doctor who says, "Look, this is what's wrong with you, and this is what you need to do to get rid of your problem" has done you a great favor. He has both accurately diagnosed your illness, and told you exactly what you need to do to be rid of the pain and suffering which brought you to his office. He's done you a great service. But a doctor who either ignores your symptoms or glosses over them, saying, "Look, everybody has aches and pains. Don't worry about them!" has done you a great disservice.
