But few of us know kids can get them, too.
Children don't necessarily get the pounding headaches and light or sound sensitivity adults experience.
But, they can have pale skin, a loss of appetite, and fatigue.
Some also have motion sickness in cars.
Doctors say it's important to find the migraine triggers.
"A kid that tells you - 'I'm having headaches' - several days a week, or fifteen, twenty days a month, you may want to know if there is any other stressor, for instance - is there anything going on in school? Any bullying occurring?" says Dr. Emad Estemalik, a neurologist at the Cleveland Clinic.
Food journals can also help determine if there are triggers in the diet.
Migraines can show up in someone as young as 4 to 6 years old.
