There are a number of theories about what causes fibromyalgia such as change in sleep patterns, serotonin deficiency (lack of the mood and sleep regulating hormone), viral infection, psychological disturbances or trauma, altered pain perception, lack of growth hormone, lack of exercise, and others.

There may be multiple factors involved in the onset of the condition and no one â€˜triggerâ€™ has been identified. However, research has shown that people with fibromyalgia tend to have disturbances in their deep sleep. There is also some evidence that certain brain chemicals are different in people with fibromyalgia.
