Signs and symptoms of fibromyalgia can vary, depending on the weather, stress, physical activity or even the time of day. Common signs and symptoms include:

- Widespread pain

- Fatigue and sleep disturbances

- Irritable bowel syndrome (IBS)

- Headaches and facial pain

- Heightened sensitivity   (to what???)

The American College of Rheumatology has established general classification guidelines for fibromyalgia to help assess and study the condition. According to these guidelines, to be diagnosed with fibromyalgia, individuals must have experienced widespread aching pain for at least three months and have a minimum of 11 locations on their body that are abnormally tender under relatively mild, firm pressure.

The new feature on MayoClinic.com also provides an overview of treatment (http://www.mayoclinic.com/health/fibromyalgia/DS00079/DSECTION=8) options, self-care suggestions, and tips to help people who have fibromyalgia cope with the condition.
