I often read up on stuff to learn the differential diagnoses, and the unique symptom combinations that could indicate a specific diagnosis.

Then I go tell a physician, and they throw it all out the window.

The pharmacist has a sign posted reading, "Your Google Search Won't Outweigh My Degrees and Qualifications." Don't try to be well-informed on biomedicine, because the knowledge will be counterproductive.

Kinda funny but I have the opposite experience. I go see my doc and tell them what I researched and often they tell me they are impressed, sometimes they tell me they think my conclusion is probably wrong and tell me why they disagree. However I am usually searching PubMed or the library at my Uni and not searching Google or YouTube.
