In IT, all the worst patients are doctors.
Hopefully no actual doctors answer this question though 🙂
I do not think it is appropriate to talk about any details, but something somewhat adjacent to this is that a lot of my colleagues didn't go into pediatrics because they hate dealing with parents.
People usually see doctors when something has gone very wrong with their life. It's scary when your body backs you into a corner, and fear makes people act stupid and angry. I would hope they could be given a little bit of slack.
I have family members who are doctors and they generally agree that the worst patients are physically/verbally abusive ones. Apart from that, they complain a lot about patients who don't follow their advice and then get angry when they don't get better.
I work in healthcare. My best patient is the guy who punched the rudest doctor in the face. If that rude doctor were in this thread, I bet he’d pick that guy.
