I do it all the time.. it is only arrogant doctors who aren't good to have anyway, who have issues with this. If your doctors are not interested in checking out the things you have or learning about them, get rid of them.
I agree with everything taniaaust1 says. In fact, many years ago I used the doctor's reaction to my bringing in information as a screening tool to select my primary care physician. She passed.
She's not a CFS/ME expert but she treats me with a basic level of courtesy and respect that ALL HUMAN BEINGS should show to one another. Sadly, many doctors "missed the memo" on this important point.
I do the same thing now when visiting a new specialist. Some doctors don't want to discuss my problems with OI (Orthostatic Intolerance, my specific diagnosis is NMH) and they don't even glance at the Johns Hopkins handout that I've brought describing the condition. Those doctors get crossed off my list for good.
What's amazing to me is how many doctors say "what's that?" when I say "orthostatic intolerance." I wouldn't mind that they don't know what it is. Doctors can't know everything!
What bothers me is that they have
no curiosity about it. The fact that they only want to know their tiny area of expertise, and nothing about other conditions that might overlap with their specialty (e.g., how OI might affect sleep, for example), is really strange to me. As a former software engineer I'm used to the idea of looking at the whole system, not just one tiny piece of it.
Edit - One caveat with this advice is that it depends on how flexible you are with doctors. If you are very limited in the doctors that you could choose (e.g., you live in an area with very few doctors, or you are on medicaid and not many doctors will take those payments, or some similar situation) then you might need to be more cautious in how you interact with your doctor. Yes, it's still wrong for doctors to be so arrogant. Yes, the doctor should at least listen to the patient (may not agree, but show the courtesy of listening). But when the doctor is in a position of power to prescribe medications, and you have limited ability to switch doctors, then you may need to consider this point more carefully.
