Chronic Pain: Is generally recognized as pain that persists past the normal time of healing or repair. In actual clinical practice, however, the time period can vary from one month to more than six months. Changes in the CNS known as central neuroplasticity may prolong and maintain pain long after the usual time of response to an acute injury. These changes make it difficult to say when.
