Final answer:
Dacryadenalgia refers to pain in the tear gland, also known as the lacrimal gland, which is located above the eye and is responsible for tear secretion.
Step-by-step explanation:
A person with dacryadenalgia has pain in their tear gland. The term 'dacryadenalgia' derives from 'dacryo-' indicating 'tear' and 'aden-' referring to a gland, combined with 'algia' which means pain. The lacrimal gland is a gland situated above the eye that secretes tears to keep the eye moist and free of debris. When there is pain associated with this gland, it is often due to inflammation or other conditions affecting the glandular tissues.
