What is it?
Fibromyalgia involves widespread pain and altered pain processing; it is not simply local joint damage.
Symptoms and important signs
Persistent widespread pain, fatigue, unrefreshing sleep and sometimes concentration difficulties.
How is it assessed?
Clinical assessment and targeted tests to exclude other causes; no single scan confirms it.
Care and treatment options
Education, gradual exercise, sleep support and individually selected treatments.
When to seek help
New weakness, fever or focal neurological symptoms should not automatically be attributed to fibromyalgia.
