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.
Migraines often initially start between the age range of 10 and thirty-five and decrease just after age 50. Most migraine headaches range between a half-hour to 6 hrs. Some can continue on as long as 2 or 3 days. The rate of recurrence differs significantly from occasional to many times a month.
