In my experience, I have had:
1. Doctors that know nothing about a really basic ailment and not have any meaningful guidance or treatment to suggest
2. Doctors that Google something literally in front of me, things that I have already Googled myself, and draw the wrong conclusion because they're looking at results at a glance - when I had searched myself earlier and dug deeper though, it was clear to me the result he was looking at was just plain wrong
3. Doctors that provide very little to no guidance about a wide selection of medications available to treat a problem, leaving me to essentially guess which option of a dozen or more I should go with
4. Doctors that force me to advocate for myself and my condition before they agree to help treat it - so much so that I had to visit 4 different doctors to find one that would, wasting nearly a thousand dollars of office visits with nothing to show for it.
It's no wonder people do their own research and dare to advocate for themselves. Most doctors are fucking worthless.
