Determine how you feel about what the doctor has said:
What are you feeling? However you feel, it is okay.
Know you can get another opinion:
Not all doctors think alike. If you need reassurance that this is the right option or you have a gut feeling that the appointment should have gone differently for any reason, find another doctor so that you can get second opinion.
Research any testing that the doctor has ordered:
If you are someone like me, I do not like to be blindsided about what is about to happen. If I do not get a chance to ask the doctor about expectations I should have for medical tests then I will research the test itself or ask those questions when the hospital calls to schedule the test.
