Brian,
Yes I understand and with all due respect to you, we had a doctor treat John a few years ago telling him that the yellow sputum he was spitting up was just flu. Unfortunately, four days later as he was rushed to the hosptial that the flu was legionaires disease. He was diagnosed by an alert first year out doctor who reviewed the symptoms including the yellow sputum. Medicine is still as much an art as a science. And yes some doctors rush to find put people on antibotics. However in Johns case by the time the tests came back, he would have been dead.
