early 15c., from Middle French lesion, from Latin laesionem (nominative laesio) injury, from past participle stem of laedere to strike, hurt, damage, of unknown origin. Originally with reference to any sort of hurt, whether physical or not.
Most migraines last about 4 hours, but severe ones can last up to a week. How often they happen differs for everyone, but itâs common to get two to four headaches per month. Some people may get migraines every few days, while others get them once or twice a year.
A migraine aura usually precedes the migraine attack but can also occur during the attack. A migraine aura can also occur without an associated headache. The migraine attack itself can last as little as four hours or as long as several days. The attack is followed by a postdrome phase, where you might feel drained or washed out.
