Oh I absolutely agree that the Internet has really empowered people to seek out the best medical care possible. Even in the pharmaceutical industry, for the first time ever, most of the promotional funds are being directed at patients (ie. ads in magazines, newspapers, TV, word of mouth) rather than physicians. In the 80s, it was most common to fly specialists out to a conference, lavish them with gifts and expensive hotel rooms and then rely on them to peddle the drug to the consumer, because the consumer oftentimes didn't know any better.
As a scientist I think you should question everything. Nothing in biology is black and white and neither should your treatment be. One of the things that has always annoyed me in the medical community is that they have a tendency to disregard what the patient is telling them about their body. We know our body the best and we know when something is off or something is wrong. And just because a test doesn't reveal it doesn't mean that you are imagining things. I have a genetic defect that was not recognized for 22 years because standard tests didn't pick it up and although I made numerous complaints to my GP and the endocrinologist, it took a long time for them to accept that sometimes bloodwork isn't all-telling.
