Inflammation of fibrous tissue and muscle cells, characterized by pain, weakness, and sometimes swelling in the affected area.
From fibro- + myo- (Greek mys, 'muscle') + -sitis (variant of -itis, 'inflammation'). This medical term emerged in the 1800s to describe combined inflammatory conditions of muscle and connective tissue.
Fibromyositis overlaps confusingly with fibromyalgia in modern medicine—both cause widespread pain, but doctors now recognize fibromyalgia as something more complex involving the nervous system, not just inflammation.
