Sorry to add to this so belatedly, but for future readers who stumble on this thread:
I can't stress enough how important it is to emphasize that *you* are in charge of your own health care. If you are expecting to be led by the hand, gingerly down the primrose path, by any physician, to the treatment that is ideal for you, you will eventually be rudely awakened by the poor care you're getting. I only speak from experience here, and I have had excellent as well as poor caregivers (note that none of them thought of *themselves* as poor caregivers, but doctors have varying personalities/philosophies/agendas). So be forewarned.
In many cases, doctors do not care how many opinions you're getting and when/where/how/whether you're getting treated at all. So don't worry about that.
In fact, it will probably be quite the opposite, and you'll find yourself ignored or slighted. You will be fortunate to find someone who pays attention enough to say more to you than "knee hurts? take ibuprofen." Physicians typically are in the business of keeping chronically ill people feeling "normal" ... they generally do not have time to address preventive methods or "optimal" health, and they do not care about "performance" related injuries due to sports and any extreme activities (like distance running) that healthy people and above-average healthy people engage in (unless you are going to see a sports-specific practitioner, and already know you are shopping for surgery).
When my wife was pregnant we went through half a dozen hospitals and doctors, who pretty much across the board acted like my wife was psycho for being a vegetarian, wanting to keep running and weight training during pregnancy. In retrospect, these doctors spend their days with hypertensive, overweight, unhealthy women, so what did we expect? My wife's health habits were already 10x better than the "prescribed" behavior the doctors were advocating. We eventually found a physician who spoke our language, but it was a long process but one I recommend going through, if you must. It is definitely worth your time to get 2nd, 3rd, and 6th, opinions, if necessary. In fact it is essential to your health in this day & age.
