[Greek] Paroxysmal pain in the region of the coccyx. It is due either to neuralgia, to rheumatism, or to disease or injury (especially fracture) of the coccyx. In the latter case there is great pain from defecation or any cause producing motion of the bone, and the coccyx frequently has to be separated from its muscular connections, or even removed altogether.
