By Mayo Clinic staffRisk factors for fibromyalgia include:
- Your sex. Fibromyalgia occurs more often in women than in men.
- Age. Fibromyalgia tends to develop during early and middle adulthood. But it can also occur in children and older adults.
- Disturbed sleep patterns. It's unclear whether sleeping difficulties are a cause or a result of fibromyalgia. But people with sleep disorders — such as nighttime muscle spasms in the legs, restless legs syndrome or sleep apnea — often have fibromyalgia.
- Family history. You may be more likely to develop fibromyalgia if a relative also has the condition.
- Rheumatic disease. If you have a rheumatic disease, such as rheumatoid arthritis or lupus, you may be more likely to develop fibromyalgia.
