Y1 - 2013 N1 - T2 - CURRENT Diagnosis & Treatment: Occupational & Environmental Medicine, 5e AB - Chronic pain is variously defined as (1) pain lasting more than 3 months, (2) pain lasting more than 6 months, and (3) pain lasting beyond the period of expected healing or persisting in the absence of injury. Chronic pain is distinguished from acute pain in a number of ways. Most concretely, it lasts longer. In many cases, though, what is genuinely unique about chronic pain is that it seems to persist even when a physical insult is not occurring, or it is out of proportion to the physical damage that has occurred.
