It is not uncommon for those who suffer from chronic pain to feel stressed and depressed at times. This is no surprise, given the fact that “chronic pain” usually means pain that lasts more than three to six months. Prolonged pain appears to set up a pathway in the nervous system that sends pain signals to the brain, even in the absence of an underlying anatomical problem.
Some chronic pain may be due to a diagnosable anatomical problem, such as degenerative disc disease or spinal stenosis, that can cause continual pain until successfully treated. More often, the chronic pain has no clear anatomical cause, as in failed back surgery syndrome or chronic back pain without an identified pain generator. In such cases, the pain is itself the disease.
