The pain is usually paroxysmal, varying in intensity, and described as shooting, stabbing, boring, burning, or deep-seated. Neuralgia is largely confined to adult life, is more frequent in women than in men, and is especially apt to occur in neuropathic individuals. It is induced by cold, exhaustion (from overwork, worry, over-lactation, mental shock, lack of food and rest), anemia, malaria, alcohol, lead, and glycohemia. In addition to this so-called idiopathic neuralgia, symptomatic neuralgia is sometimes used to designate neuralgiform pains inciSee dent rai game the adjectiv Ciliary, intercostal, etc., neuralgic (nu-ral'jik), a.
