  • The deep phase of sleep may be disrupted and affect the amount of hormones that your body releases.

Many people connect the beginning of their symptoms to a certain event, such as the flu, an injury or surgery, or emotional trauma and stress. An event of this type combined with other things, such as increased sensitivity to pain and sleep problems, may lead to fibromyalgia in some people.
