Fibromyalgia is a complex disorder characterized primarily by chronic widespread pain, fatigue and other physical and cognitive symptoms. Although it affects millions of people worldwide, the underlying biological mechanisms are not yet fully understood. Now, a study by the University of Barcelona suggests that neuroimmune alterations in the central nervous system may play a key role in the development and progression of this condition.
