[Functional somatic pain syndromes-nomenclature]

A significant number of pain syndromes to be found in all medical specialties, including pain therapy, can be ascribed to a group that according to the classification of the International Association for the Study of Pain (IASP) is referred to as "pain syndromes with dysfunctional etiology," or according to internal medical terminology as "functional somatic syndromes" (functional disorders), or based on psychiatric nomenclature as "somatoform disorders." Frequent syndromes exhibiting pain as the major symptom include fibromyalgia syndrome (FMS), irritable bowel syndrome (IBS), chronic pelvic pain (CPP), tension headache, chronic myoarthropathies of the masticatory system (MAP), and prostatodynia. It is important for practitioners of both somatic and psychosocial medicine to be aware of the terminology used in other fields and the frequency of comorbidities of the individual syndromes. To improve communication between somatic and psychosocial medicine as well as with patients, the authors recommend that pain therapists base their diagnosis on the ICD-10 classification and refrain from using a separate pain therapy nomenclature.
