Fibromyalgia syndrome is a condition where pain occurs in muscles and surrounding structures without any obvious tissue damage. The pain is usually widespread and people often experience fatigue.

Fibromyalgia affects mostly women, between the ages of 35 to 60 years, from all nationalities and culture groups. It can also affect children.

The symptoms of fibromyalgia can go up and down. Many people find the symptoms are worst first thing in the morning and last thing at night. The symptoms can be mild, moderate or severe. There may be extended periods of time – perhaps even years – when symptoms disappear. Other people have pain every day, or there may be variations between these two extremes.

The cause or causes of fibromyalgia are not known. There is no cure but treatment can help some symptoms.
