Chronic daily headaches are defined as tension-type headaches or migraines that occur more than 15 days a month. Chronic headaches or migraines can be caused by a number of factors. Those causes could include head trauma, illness and infection, dietary habits, genetic factors, overuse of certain pain medicines, coexisting psychiatric problems and, on more rare occasions, brain problems. Chronic headaches or migraines can occur in children or adults.

The symptoms experienced by children and adults not always the same. As an example, adults can often experience migraine pain for at least four hours, while a migraine in children could last for a shorter time period. However, the symptoms in children can still be severe. Symptoms of migraines in children can include vomiting, light sensitivity, and abdominal pain. Tension headaches can often cause soreness in neck or head muscles.
