I had a primary care doc here who became annoyed with me because I explained that I research the internet before our appointment. He clearly felt aback about it. I did not judge why because it was clear that the relationship was not going to work.
Conversely, I now use my cardio guy as my primary. He encourages me to search the net so that we can converse concerning the ways and hows, etc.
I will always defer to my doc he/she is the expert but I do want to know and I do want input and I do want the satisfaction of knowing I was active in my treatment, etc. And the bonus for me is my doc separates the internet shaft from the wheat because I remember that old saw of "I know enough to get myself into trouble but not enough to get myself out."
