ABSTRACT
Although much has been learned over the last decade about fibromyalgia, much remains to be learned about its causes, nosology, treatment, and overlap with a variety of rheumatic and nonrheumatic conditions. Advances in rheumatology, cardiovascular medicine, endocrinology, epidemiology, immunology, infectious diseases, neurology, psychiatry, and psychology have served as the basis for the formulation of new lines of research and novel therapeutic interventions. The purpose of this review is to summarize the knowledge gained and published mainly within the last decade.
