I go to Cleveland Clinic and have experienced doctors having differing opinions but they explain their rationale. They usually are in agreement but might have different philosophies about risk/reward balance. I tend to be more conservative as to risk (it being my body that deals with unintended consequences!) so appreciate their explanations. Even good doctors can disagree. My idea of a bad doctor is one who doesn't like being questioned or working as a team. (Because it's my body that deals with the consequences. A refrain that I keep uppermost in my head when making medical treatment decisions. I hope to never be eligible for participation in some malpractice or drug-maker lawsuit.)
