There tend to be two variables, or standards, maybe I'm missing the right word? ...but two things I like to think about, when I am with any dr. or health care professional. There's how intelligent they are, and then there's how much they care about me, and in terms specifically about or for, how much they're willing to try & put in the effort to solve the problem that is me. For example, you can have the most brilliant dr. on earth, theoretically. But if he doesn't find you worth his, or your salt, then it isn't going to probably do you very much good. Say if he or she, doesn't or don't / won't listen to you. Answer your questions, etc. Or you can have someone who is pretty smart. But they will go to the end of the Earth to try & help you. Some acceptable blend of both, or formulated calculation that you can live with, and be happy & content by, is what's going to ultimately probably be best (for you) & to provide you with, or yield the most satisfying results. I have found anyway, but that said, I'm pretty abnormal. And so I don't think that many of my experiences, would transfer on over to yours, and therefore - then - be applicable
