Let's remember one doctor cannot know everything about everything. Alot depends on their medical education, experiences with patients, conference participation, interaction with other doctors and the individual research each doctor does. Like the rest of us doctors will always be better in the areas they have personal interest in just because they will be drawn to those subjects more than other subjects.
By all means if you think a doctor is not your best advocate it is time to find another doctor who can do his or her best for you. Be proactive. Be assertive. Our health and our bodies are our responsibility. It is up to each one of us to do our parts and take care of ourselves to the best of our ability 24/7. It is up to us to ask questions and discuss our concerns with our docs. It is up to us to learn as much as we can about our health problems. Solving health problems should be a team effort between doctors and patients.
