Maybe a bit of clarity is in order here. To start let us define your provider's role. The person is an advisor and, in many cases, a techician who performs repair and maintenance on your body. But, as long as you are mentally competent you, and no one else unless you so designate, make the final decisions on all matters concerning your body. Bet your boots your doc knows that. That is why you have to sign many of the forms you do.

Your role is to listen to your doc. If you don't understand what the doc says ask again. If you still don't understand ask for some references so you can research without wasting anybodys time. If you need to see another doc. Understand that almost every drug or procedure has benefits and risks. It is up to you to make the final decision on how that balance affects you and how you live your life.

Yep, that means you can't just walk in the door and tell the doc: "Fix me". But, the ultimate outcome for both of you will be much better.

As for second opinions: It does pay to ask around. Your doc's office is a business like any other business and is primarily judged by its' profitability. That influences how the doctors practice. So, yes, shop around until you are satisfied that you are getting the best answer before making any drastic changes in your life.
