Etymology: "Algesthesis" is a technical coinage built from two Greek elements. The first, "algos", means "pain" (it also appears in words like "neuralgia", where the pain is in a nerve), and the second, "aisthesis", means "perception" or "sensation", the same root that gives English "anaesthesia" and "aesthetic". Put together, the word names the bodily capacity for sensing pain. Because it is assembled from classical parts to describe a physiological function, it belongs to the same family of scientific vocabulary as "anaesthesia", which was likewise coined from Greek by modern writers rather than inherited from antiquity. Ancient Greeks had no word meaning exactly "the perception of pain as a faculty", so the term is a product of later scientific naming, using the old roots to label a concept that was studied in modern physiology.
