Migraineurs aged 5 to 10 years experience headache, nausea, abdominal cramping, vomiting, photophobia (sensitivity to light), phonophobia (sensitivity to sound), osmophobia (sensitivity to smells), and a need to sleep. They usually fall asleep within an hour of the time the attack starts. The most common accompanying symptoms include paleness with dark circles under the eyes, tearing, swollen nasal passages, thirst, swelling, excessive sweating, increased urination, and diarrhea. Older children tend to present with headache on one side. Many sinus headaches are really of migrainous origin. The headache location and intensity often changes within or between attacks.
