There is currently no evidence to suggest that viruses cause fibromyalgia. While some people with fibromyalgia may report experiencing symptoms following a viral illness, such as the flu or a cold, there is no definitive link between viral infections and the development of fibromyalgia.
Fibromyalgia is a chronic condition that causes widespread pain, fatigue, and tenderness in the muscles and joints. The exact cause of fibromyalgia is not fully understood, but it is thought to involve a combination of genetic, environmental, and psychological factors.
Some research has suggested that fibromyalgia may be associated with abnormalities in the way that the brain and nervous system process pain signals, as well as changes in the levels of certain neurotransmitters and hormones in the body. However, there is no single virus or other infectious agent that has been identified as a direct cause of fibromyalgia.
