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.
Migraine duration also depends on the type of migraine you have: 1  An optical migraine causes visual disturbances such as zigzags or blind spots or blurred vision often in one eye, but no headache pain; it typically lasts an hour or two. 2  Classic migraines, which start with a warning sign or aura and can be quite painful, can last a day or two. Common migraines, those that do not have auras first, can last three or four days. With this type of migraine, the pain in your head may be only on one side. When migraine duration is longer than three or four days, itâs called status migrainous and requires immediate medical attention because it increases your risk of stroke, Mauskop says.
