The most important thing you should get out of your appointment with the doctor is an adequate explanation to the problem which prompted your visit.
Write down your questions in the order that you feel is the most important. Write down, or ask your doctor to write down, the answers to your questions, including instructions for the use of prescription and over the counter medications, medical devices, and lifestyle changes. If there isn't enough time to have all of your questions answered, then you will have had the most important ones addressed, and could save the rest for the next visit.
