Pain
An unpleasant sensation induced by noxious stimuli which are detected by NERVE ENDINGS of NOCICEPTIVE NEURONS.
Acute Pain
Intensely discomforting, distressful, or agonizing sensation associated with trauma or disease, with well-defined location, character, and timing.
Year introduced: 2012
Pain Management
A form of therapy that employs a coordinated and interdisciplinary approach for easing the suffering and improving the quality of life of those experiencing pain.
Breakthrough Pain
Acute pain that comes on rapidly despite the use of pain medication.
Pelvic Girdle Pain
Discomfort associated with the bones that make up the pelvic girdle. It occurs frequently during pregnancy.
Musculoskeletal Pain
Discomfort stemming from muscles, LIGAMENTS, tendons, and bones.
Chronic Pain
Aching sensation that persists for more than a few months. It may or may not be associated with trauma or disease, and may persist after the initial injury has healed. Its localization, character, and timing are more vague than with acute pain.
Visceral Pain
Pain originating from internal organs (VISCERA) associated with autonomic phenomena (PALLOR; SWEATING; NAUSEA; and VOMITING). It often becomes a REFERRED PAIN.
Nociceptive Pain
Dull or sharp aching pain caused by stimulated NOCICEPTORS due to tissue injury, inflammation or diseases. It can be divided into somatic or tissue pain and VISCERAL PAIN.

Labor Pain
Pain associated with OBSTETRIC LABOR in CHILDBIRTH. It is caused primarily by UTERINE CONTRACTION as well as pressure on the CERVIX; BLADDER; and the GASTROINTESTINAL TRACT. Labor pain mostly occurs in the ABDOMEN; the GROIN; and the BACK.

Patellofemoral Pain Syndrome
A syndrome characterized by retropatellar or peripatellar PAIN resulting from physical and biochemical changes in the patellofemoral joint. The pain is most prominent when ascending or descending stairs, squatting, or sitting with flexed knees. There is a lack of consensus on the etiology and treatment. The syndrome is often confused with (or accompanied by) CHONDROMALACIA PATELLAE, the latter describing a pathological condition of the CARTILAGE and not a syndrome.
Flank Pain
Pain emanating from below the RIBS and above the ILIUM.
Year introduced: 2001
Complex Regional Pain Syndromes
Conditions characterized by pain involving an extremity or other body region, HYPERESTHESIA, and localized autonomic dysfunction following injury to soft tissue or nerve. The pain is usually associated with ERYTHEMA; SKIN TEMPERATURE changes, abnormal sudomotor activity (i.e., changes in sweating due to altered sympathetic innervation) or edema. The degree of pain and other manifestations is out of proportion to that expected from the inciting event. Two subtypes of this condition have been described: type I; (REFLEX SYMPATHETIC DYSTROPHY) and type II; (CAUSALGIA). (From Pain 1995 Oct;63(1):127-33)
Year introduced: 2000

Pain Clinics
Facilities providing diagnostic, therapeutic, and palliative services for patients with severe chronic pain. These may be free-standing clinics or hospital-based and serve ambulatory or inpatient populations. The approach is usually multidisciplinary. These clinics are often referred to as acute pain services. (From Br Med Bull 1991 Jul;47(3):762-85)
