Management of fibromyalgia, a distinct rheumatologic syndrome.
The pathophysiology and management of fibromyalgia, a unique nonarticular rheumatologic syndrome characterized by diffuse musculoskeletal aches and pains, stiffness, discrete tender points at typical soft-tissue sites, and a characteristic sleep disturbance, are reviewed. The prevalence and incidence of fibromyalgia are not known, but it is one of the most common conditions seen by rheumatologists (after degenerative joint disease and rheumatoid arthritis). It was previously thought to involve inflammation of fibrous intermuscular septa and is sometimes referred to in the literature as fibrositis. It is not primarily psychogenic, but psychological factors may contribute. The tender points are the key to diagnosis. Fibromyalgia may be classed as primary (when no underlying disease is present) or secondary (when an associated condition exists). The pathophysiology of fibromyalgia is unknown but appears to involve complex interactions of central neurotransmitters with a relationship to pain perception, mood, and sleep. Treatment is empiric; nondrug treatment involving education, relaxation, and increased physical activity is essential. Few controlled trials of drug therapy have been conducted. Analgesics, anti-inflammatory drugs, phenothiazines, tricyclic antidepressants, and the tricyclic muscle relaxant cyclobenzaprine have been used; low doses of amitriptyline or cyclobenzaprine provide increased control of pain and mood.(ABSTRACT TRUNCATED AT 250 WORDS)
