 Before your next medical appointment, write down any questions you have with the most important ones first and make a list of every medication you take, even over-the-counter medicines and vitamins, and bring it with you. Make sure you ask your questions and really understand what the doctor or nurse is telling you before you leave. Write it down if you need to and be sure to ask if you don't understand something. You wouldn't leave the body shop with questions for your mechanic, so you shouldn't leave a medical appointment with questions still on your mind.
