Oh and you do need to do your homework and learn more about possible conditions and what your tests mean. It's smart to be an advocate because most doctors don't have the time to do that for all of their patients. My advice when bringing your new found wisdom to doctors is to tread lightly. Most people don't want to be told what to do so I've learned to weave my symptoms, test results and any new knowledge intricately into an in person conversation at my visit. It's about timing and feeling desperate but not acting desperate. If that makes sense.
