" Pain is a Medical Orphan. Perhaps because it has traditionally been considered the consequence of disease or injury, not an illness in itself, and not specific to a body organ or site, no single specialty has accepted, as a pressing goal or major responsibility, a commitment to the elimination of pain. Perhaps there’s a little too much “man up” sentiment out there, embracing the words of Nietzsche: “That which does not kill us makes us stronger. "
