A childâs tension-type headache is frequently caused by tension or stress, depression, or insufficient rest. Tension-type headaches do not have the hereditary factor that migraines do, and they are not caused by organic problems or serious diseases.
But a migraine is worse than a regular headache. Migraines usually occur about one to four times a month. The pain is often throbbing and can happen on one or both sides of the head. Kids with migraines often feel dizzy or sick to their stomachs. During the headache, some kids are sensitive to light, noise, or smells, and want to sleep. When they wake up, they usually feel better. Most migraines last from 30 minutes to 6 hours but some can last a day or two.
