Fibromyalgia is a complex chronic pain condition that affects the muscles and soft tissues of the body. While the exact cause of fibromyalgia is not fully understood, it is believed to be related to abnormalities in the way the brain and spinal cord process pain signals.
The pain experienced in fibromyalgia is often described as a deep, aching, or burning pain that can be felt in multiple areas of the body. This pain can be accompanied by other symptoms such as fatigue, sleep disturbances, and cognitive difficulties.
While fibromyalgia is primarily considered a pain condition, it is not strictly a nerve or muscle pain. Rather, it is believed to be caused by a dysfunction in the way that the brain and spinal cord process pain signals, which can affect both nerves and muscles.
