I meant that you can discuss it with your doctor to get their factual knowledge or pointers, and then draw your own conclusions. I didn't say, and didn't mean to say (sorry if it came across like that), that you should follow their advice to any degree. I trust the overwhelming majority of people (doctor or patient) to use their own reasonable judgement, and the rest won't be helped by this advice anyway.

And for what it's worth, you may have had a string of bad doctors. I never had that feeling with any of mine (though I've only ever seen doctors in the Netherlands and Germany).
