Everyone is human. I don’t trust doctors any more than I trust lawyers, mechanics, strangers, etc etc etc. American society places doctors on an undeserved pedestal. That said, obviously if you need treatment and that treatment requires flashing a doc I’m sure you’ll oblige. You need to be informed about the problem and what needs to be done to rectify it and make an educated decision on your own treatment rather than just blindly following a doc. When I walk into a hospital, I already have an educated theory on what is wrong and usually don’t even need it confirmed (that’s how certain I am), just need the treatment. It’s easier to be prepared obviously when it isn’t a dire emergency. In that case, you probably just have to trust that most people are decent.
