The nature of attacks varies between children and from time to time in the same person. Visual disturbances may last several minutes or several hours, but they disappear once the headache begins. Dull, boring pain in the temple that spreads to the entire side of the child's head. Pain becomes intense and throbbing. Nausea and vomiting.
Some children become pale, with bloodshot eyes and a runny nose or eyes.
Vision disturbances occur when blood vessels narrow. Headache begins when they widen again. Emotional problems are probably the most common reason for migraine attacks, but headaches don't necessarily coincide with emotional upset. They often occur on weekends, when a child's stress is decreased. Use of contraceptives.
