The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
