An abdominal migraine is an extreme form of headache mainly seen in children 5-9 years of age. This condition can also occur in adults. Typically lasting anywhere from 2-72 hours, the main symptoms are abdominal pain and nausea accompanied by vomiting. Loss of appetite and an abnormal skin pallor may also be present. The pain is located in the middle of the stomach centered around the belly button. Research suggests that this condition is associated with migraines: typically sufferers have family members that suffer from migraines and children who experience abdominal migraines will frequently experience migraines as adults, not experiencing them before they are teenaged and eventually developing into full-blown migraine headaches.
