Fibromyalgia is a medical syndrome that causes chronic widespread pain, accompanied by fatigue, awakening unrefreshed, and cognitive symptoms. Other symptoms can include headaches, lower abdominal pain or cramps, and depression.[9] People with fibromyalgia can also experience insomnia[10] and general hypersensitivity.[11][12] The cause of fibromyalgia is unknown, but is believed to involve a combination of genetic and environmental factors.[4] Environmental factors may include psychological stress, trauma, and some infections.[4] Since the pain appears to result from processes in the central nervous system, the condition is referred to as a "central sensitization syndrome".[4][13] Although a protocol using an algometer (algesiometer) for determining central sensitization has been proposed as an objective diagnostic test, fibromyalgia continues to be primarily diagnosed by exclusion despite the high possibility of misdiagnosis.[14]
Fibromyalgia was first defined in 1990, with updated criteria in 2011,[4] 2016,[9] and 2019.[12] The term 'fibromyalgia' is from Neo-Latin fibro-, meaning 'fibrous tissues'; Greek μυο- myo-, 'muscle'; and Greek άλγος algos, 'pain'; thus, the term literally means "'muscle and fibrous connective tissue pain'.[15] Fibromyalgia is estimated to affect 2 to 4% of the population.[16] Women are affected about twice as often as men.[4][16] Rates appear similar across areas of the world and among varied cultures.[4]
The treatment of fibromyalgia is symptomatic[17] and multidisciplinary.[18] The European Alliance of Associations for Rheumatology strongly recommends aerobic and strengthening exercise.[18] Weak recommendations are given for mindfulness, psychotherapy, acupuncture, hydrotherapy, and meditative exercise such as qigong, yoga, and tai chi.[18] The use of medication in the treatment of fibromyalgia is debated,[18][19] although antidepressants can improve quality of life.[20] Other medications commonly considered helpful in managing fibromyalgia include serotonin–norepinephrine reuptake inhibitors, nonsteroidal anti-inflammatory drugs, and muscle relaxants.[21] Q10 coenzyme and vitamin D supplements may reduce pain and improve quality of life.[22] While symptoms of fibromyalgia are persistent in nearly all patients, they are not caused by cell damage or any organic disease.[19]
