Head trauma. Even after trivial head trauma it is not unusual to experience headaches or scalp tenderness for a week or two. However if headaches persist or increase in intensity and frequency, or if there is accompaning nausea,dizziness,drowsiness,visual disturbances get evaluated for brain injury or bleeding.
