My doctor actually appreciates that I go to primary and other reliable sources, read up on my conditions, and understand the standard of care and other appropriate courses of action. What he can't stand is people who "do their own research" on, like, InfoWars.

I treat my doctor as a subject matter expert/collaborator, which means that if I come to him with (for example) "what if it's lupus?" and he says "it's probably not lupus", I usually let the matter drop.
