Write out a list of questions. Know your priorities so that you can negotiate what will be covered if the list is too long for a single appointment. Arrange another appointment for what is not covered. Participate in decisions about your care. When I ask for input, I am trying to include you as the expert on yourself .
Most decisions have pros and cons.
The same things and will not necessarily make the same decision. Be clear about what you want from your doctor. If you really want a prescription for an antibiotic, or a specific test, let the doctor know that. She may say no, but you are more likely to learn the reason for the no instead of just leaving with the feeling that you didn't get your needs met. Similarly if there is something you are really worried about, or need an explanation for, ask about it.
