Pain located in or around an antrum, particularly the maxillary antrum (sinus cavity in the cheekbone).
Combines 'antrum' (cavity) with '-algia' (pain, from Greek algos). This medical term developed in 19th-century diagnostic medicine as doctors sought precise terminology for specific types of pain related to anatomical structures.
Before modern imaging, doctors had to diagnose antralgia mainly through patient symptoms and physical examination, which made it tricky because antral pain can feel very similar to dental pain or migraine headaches.
