Do I trust the medical profession?

In a word, no. I don't. There is a treatment bias to the medical profession. They really aren't interested in understanding what is wrong with a patient. They are totally uninterested in understanding what caused it. They are interested in how to treat "what is indicated" to the point that they will apply a treatment, see if it works and then decide after the fact what was truly wrong.

I liken it to a mechanic with a wall of parts. You bring your car in complaining of something. He listens for a bit, gets in the car, does some diagnostics to the point that he has an idea of what part on the wall to grab. He installs that part and sees if it makes it better. If it does then that must have been the problem. If it doesn't then you still get the bill.
