What causes Fibromyalgia?

The exact cause is unknown, but it is thought to be related to abnormal levels of certain chemicals in the brain and changes in the way the central nervous system (brain, spinal cord and nerves) process pain messages carried around the body. 

In many cases it appears the condition is triggered by a physical or emotionally traumatic event, such as:

* injury or infection

* giving birth

* having an operation

* breakdown of a relationship

* death of a loved one 

Anyone can develop FM, although it affects around 7 times more women than men. Usually between the ages of 30 and 50 but also affecting children and the elderly. 1 in 20 people could be affected by the condition.
