I recently went through a very similar experience as yours and agree that the medical sites provided by Google are basically pamphlet material. It has indeed become very hard to get detailed, complex information from simply googling things, to the point that I don't trust getting valid info from a google search. Instead, I look for books by authors that are cross-referenced by multiple sources, I look at forums to see what different people agree/disagree on. In other words, I like to look at people from different backgrounds and places agreeing on similar issues or facts to confirm that the possibility of information being true is larger than otherwise.
