Fibromyalgia Causes

Doctors don't know what causes fibromyalgia, but it most likely involves a variety of factors working together. These may include:
Genetics. Because fibromyalgia tends to run in families, there may be certain genetic mutations that may make you more susceptible to developing the disorder.
Infections. Some illnesses appear to trigger or aggravate fibromyalgia.
Physical or emotional trauma. Post-traumatic stress disorder has been linked to fibromyalgia.
Why does it hurt?Current thinking centers around a theory called central sensitization. This theory states that people with fibromyalgia have a lower threshold for pain because of increased sensitivity in the brain to pain signals.
Researchers believe repeated nerve stimulation causes the brains of people with fibromyalgia to change. This change involves an abnormal increase in levels of certain chemicals in the brain that signal pain (neurotransmitters). In addition, the brain's pain receptors seem to develop a sort of memory of the pain and become more sensitive, meaning they can overreact to pain signals.
