Fibromyalgia is a disorder that causes muscle pain and fatigue. People with fibromyalgia have "tender points" on the body. Tender points are specific places on the neck, shoulders, back, hips, arms, and legs. These points hurt when pressure is put on them.
Symptoms of fibromyalgia include:
- Widespread pain - The pain associated with fibromyalgia often is described as a constant dull ache that has lasted for at least three months. To be considered widespread, the pain must occur on both sides of your body and above and below your waist.
- Fatigue - People with fibromyalgia often awaken tired, even though they report sleeping for long periods of time. Sleep is often disrupted by pain, and many patients with fibromyalgia have other sleep disorders, such as restless legs syndrome and sleep apnea.
- Cognitive difficulties - A symptom commonly referred to as "fibro fog" impairs the ability to focus, pay attention and concentrate on mental tasks.
The exact cause of fibromyalgia is unknown, but it’s 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) processes pain messages carried around the body.
It’s also suggested that some people are more likely to develop fibromyalgia because of genes inherited from their parents.
