The human body is an extraordinary thing. Even the most experienced doctors are sometimes surprised by the things it can do. In the U.S., 30 million people (half of them children) have rare diseases, and doctors may not know how to treat them every time.
Then, there are urgent cases where the body undergoes a trauma so severe or distinct that some medical professionals may have never seen before.
One netizen was curious to know what doctors do in such situations, so they asked: "Medical professionals of Reddit, when did you have to tell a patient, 'I've seen it all before' to comfort them, but really you had never seen something so bad or of that nature?"
