Everyone needs a medical advocate these days. If you have to be an advocate for yourself, that can be hard, but not impossible. The most important thing to know is that there is a lot of misinformation on the Internet. Yes, there are some excellence sources, such as the Mayo Clinic and a few others. Medical journals can also have incorrect information and if you are not medically trained, I would stay away from medical journals.
Before you visit a doctor, I would write out your questions. One woman told me she makes two copies and gives one to the doctor when she arrives. If the doctor turns your care over to a nurse practitioner and does not see you at all, I would find another doctor. A good nurse is worth his or her weight in gold, but unless an M.D. oversees what a nurse practitioner does and writes any needed prescriptions, a lot can go by the wayside. I would always ask why a particular test needs to be done, the purpose of any X-ray, or procedure. For a complete physical examination you want to be sure a complete blood count, blood panel, and urinalysis are ordered. If you need a flu shot, pneumonia immunization,or Shingles vaccine, these should also be done or dates set up for them to be given.
If prescriptions are ordered, I would want to be sure they don't react with any other medications you are taking. Also, I would want to know if any prescribed medications have side effects you should watch for. Also, check to see if any medicine that is prescribed should be taken with food or on any empty stomach. If you ever have a bad reaction from a prescription, I would call the doctor immediately, even on a weekend.
