'antralgia' originates from Greek, specifically the words 'antron' and 'algos', where 'antron' meant 'cavity, cave' and 'algos' meant 'pain'.

'antralgia' was formed in medical Neo-Latin/Modern English from the Greek roots 'antron' + 'algos' and has been used as a technical term in medicine to denote pain in an antrum.

Initially it meant 'pain in a cavity/antrum' and the meaning has remained largely the same in medical usage, often applied to the maxillary antrum (sinus).
