Thousands of medical textbooks have been written, establishing a blueprint for how the human body is meant to work, how the heart is supposed to beat, and how skin is supposed to skin.
But every now and then, doctors come across a patient who doesn't follow the script, much like the hit ER drama The Pitt, where every episode sees a new medical curveball.
Some medical stories begin with something small, maybe a strange mark on the body or an odd reaction to something so normal. These small oddities led to the strangest medical mysteries, including a woman who spent years getting “drunk” without ever touching alcohol, and a boy whose pain couldn’t be explained by 17 doctors.
