A migraine headache is a special kind of headache. It can last for several days. It may cause intense pain. You may also feel sick to your stomach or have eye problems.
Some people start to have migraines when they are children.
Others may not have them until later in life. The headaches may come back from time to time all through life. Women are much more likely to have them than men. Migraines can also run in families. A migraine happens when brain chemicals don't stay balanced.
