The problem with challenging doctors is that the body is incredibly complex, and is not really under any obligation to "make common sense" / be bro-science-y.
The vast majority of the time you're going to be wrong and annoying, even if you're consulting LLMs first.
If a doctor is making a mistake, and you're a lay-person, you're not likely to spot it. But you are likely to challenge a bunch of things that the doctor is right and just be an annoying back-seat driver.
You're better off trying to get a doctor you can trust than treating your doctor like someone who isn't good at their job.
There are bad and shady doctors to be sure, but they are extreme outliers.
Doctors, unlike lawyers, typically care about your care - whereas lawyers are mostly interested in extracting as much of your money into their pocket as possible.
Unless you're going to some elective surgeon, most doctors are so busy, they don't need to make up pretend bs to have you come back and get work.
Lawyers on the other hand...
