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.
Tension headaches typically don't cause nausea or vomiting, and they're usually not made worse by physical activity â which is another thing that can happen with migraines. Most migraines last anywhere from 30 minutes to 6 hours. Some can last as long as a couple of days.
