“The fifth vital sign” was a “concept, not a guide for pain assessment,” one report read. Along with the pain number scale, a doctor ought to ask numerous questions about a patient’s pain history, the pain’s location, severity, impact on daily life, as well as the patient’s family history, substance abuse, psychological issues, and so on. In fact, pain was really not a vital sign, after all, for unlike the four real vital signs it cannot be measured objectively and with exactitude.
