Martin v. Nova Scotia (Workers’ Compensation Board),  2003 SCC 54 (CanLII) has told us that there is no authoritative definition of chronic pain. It is, however, generally considered to be pain that persists beyond the normal healing time for the underlying injury or is disproportionate to such injury, and whose existence is not supported by objective findings at the site of the injury under current medical techniques. Despite this lack of objective findings, there is no doubt that chronic pain patients are suffering and in distress, and that the disability they experience is real.
