If the period of the headache of a migraine attack lasts longer than 72 hours despite treatment it is called status migraenosus. Usually status migraenosus only occurs after a long lasting migraine disorder of several years in combination with constant medication overuse. Before a doctor is consulted, the patient has had at least 3 days with distinct nausea, vomiting and very high pain intensity. Self-medication during that time, often with a wide array of several different substances, did not show any success.
To end a status migraenosus, a short-time treatment with cortisone is often necessary.
