What does somesthesia mean?
Somesthesia is the perception of sensations originating in the body, with particular reference to the ability to feel pain or tenderness. The term is used chiefly in medicine, physiology, and neurology, especially when describing changes in bodily sensitivity caused by injury, nerve damage, disease, or medical treatment. In a clinical context, reduced somesthesia may indicate diminished perception in a particular area, while increased somesthesia can describe exaggerated sensitivity to pain. Although the word is uncommon in everyday English, its related adjective, somesthetic, appears in specialized discussions of sensory perception. Somesthesia is built from Greek roots meaning “body” and “sensation or perception,” making its meaning both precise and memorable: it concerns feeling as experienced through the body rather than through the senses such as sight or hearing.

Somesthesia literally means “body feeling”: it names the ability to perceive sensations arising within the body, particularly pain.

Where does somesthesia come from?
Somesthesia combines Greek sōma, meaning “body,” with aisthēsis, meaning “sensation” or “perception.” The compound was formed within the vocabulary of modern medical and physiological description. Its relatives include the adjective somesthetic and related terms such as anesthesia, which denotes the absence of sensation.
