There you are, alone, seated at your computer. You are starting to break a sweat as you are sucked into the black hole that is internet medicine. You started out at fatigue and you ended up at cancer. As I tell people all the time, I may not be an MD, but I am a WebMD. This quest has on occasion led to a relatively accurate self-diagnosis. More often than not, however, the “every symptom you have may be cancer” vortex sucks me down the rabbit hole. One click leads quickly, sometimes fatally, to another.
