This outdated term for fibromyalgia was introduced in 1904 by Sir William Gowers to describe the inflammation of fibrous tissue in his description of low back pain.
A contemporary of Gowers named Ralph Stockman supported Gowers' research by finding inflammation in muscle tissue. However, subsequent studies of muscle biopsies have failed to reproduce Stockman's findings of inflammation, and the term "fibrositis" is therefore considered a misnomer.
