Welcome to NHS Direct Online: "Fibromyalgia is a complex chronic (long-term) condition. Around 9 out of 10 people affected are women. It can affect people of all ages but is more common in older people.
The condition name comes from the Latin word fibro; meaning fibrous tissues (tendons, ligaments), ‘my’ meaning muscles, and ‘algia’ meaning pain. It used to be known as fibrositis, which literally meant inflammation of the muscles and soft tissue but was renamed fibromyalgia in the 1980s because studies found there is no inflammation or nerve injury.
Full recovery is very uncommon and the likelihood of recurrence is high. The condition is not necessarily physically debilitating, and with good support and treatment it may not severely damage quality of life. Fibromyalgia does not reduce life span."
