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.
I've had migranes last anywhere from 3 to 6 weeks already with no relief from any drugs, diet or exercise. It just had to run it's course. Typically these migraines are triggered by a change in the weather for me; and no relief even when the weather 'evened out'. It was just a chain reaction that couldn't be stopped.
