(HealthDay News) -- Most everyone suffers from an occasional headache. But frequent, severe headaches could be an indication of a more serious health problem.

The Womenshealth.gov Web site says these warning signs should prompt a visit to your doctor:

  • Headaches that occur multiple times each month and persist for hours or days.
  • Headaches that are so severe that work, school and home life are affected.
  • Headaches accompanied by tingling or numbness, changes in vision, vomiting or nausea.
  • Headaches accompanied by pain surrounding the ear or eye, convulsions or stiffness in the neck.
  • Losing consciousness or feeling confused during headaches.
  • A headache that follows an injury to the head.
  • Headaches that suddenly occur when you've rarely had headaches in the past.
