You are missing steps #1-3. Imagine you are a semi-unconscious emergency room patient complaining of severe headaches. Do you want the doctors to immediately open up your skull to see if there is anything wrong with your brain (because your head is what you are complaining about)? That would be step #4. Or do you want them to start with taking your temperature and blood pressure? That would be steps #1-3.
