-algia Also -algic.
Pain, usually in a specified part of the body.
[Greek algos, pain.]
Most words ending in -algia are specialist medical terms, but a few are more generally known, such as neuralgia, intense intermittent pain along the course of a nerve.
One that seems not to fit here is nostalgia, a sentimental longing or wistful affection for the past; this first entered the language meaning homesickness (Greek nostos, return home), hence having a sense close to ‘pain of separation’.
A few terms have linked adjectives in -algic, for example arthralgic, myalgic, neuralgic, and nostalgic.
