Annamaria,
I agree completely. Certainly one doctor's opinion is not sufficient in most cases. And you have to feel you have their attention and they care about you as an individual, not just number 3 for the day. I have read several medical journal articles about this also. There are a few recent ones I wanted to get a hold of, but don't pay for them. I used to have free access at my old job as a medical writer. I edited these types of documents and so I can read them just fine, but I can't spend the money to get them now. The abstracts offer a good synopsis of the findings, though often miss what might be the one vital bit of information for you.
As others have noted though, don't get burned out with information overload. It can be very stressful and drive you crazy. If you are pretty sure in your gut that you are leaning one direction or another as far as type of treatment, seek out the best in that field and get a couple of consults. You'll know when it feels right.
Best wishes,
Connie
