Before the 17th century, the joint pain which was thought to be caused by viscous humours seeping into the joints was always referred to as gout, a word adopted in Middle English from Old French gote "a drop; the gout, rheumatism", not to be confused with the present day specific term referring to excess of uric acid.The English term rheumatism in the current sense has been in use since the late 17th century, as it was believed that chronic joint pain was caused by excessive flow of rheum which means bodily fluids into a joint.
