Be honest with your doctor and yourself. The practice of medicine is complex enough without adding mind reading to the relationship. The more involved you are in your own care the more the physician will be involved. Most importantly you must understand both diagnosis and treatment. The old wisdom still holds, there are no dumb questions except for the one that never got asked.
Doctors tend to believe the first thing a patient says is the most important.
Realize that you may not get all of our concerns addressed in one visit, but by being organized the most important issues will be dealt with. Your physician needs to process a lot of complex information in a very short period of time. How long does it last. How often does it occur. Also attempting to get years of medical issues resolved in one office visit often only clouds the picture for issue that brought you to the doctor.
