This comment is so out of touch with the reality of the current medical system that I think you're in for a very rude awakening in the future. I can go on for days about all the stories I have to counteract this point. Even doctors themselves are feeling the diagnostic failure issues. My child's pediatrician went into the ER and said "I think my appendix is about to burst". They thought she was just being dramatic and they wanted to discharge her with Zofran and tell her to come back if it got worse. After hours of arguing with the ER doctors and nurses, she convinced them to do imaging. Boom, appendix about to burst. She had an operation 2 hours later.
