When to call your doctor
• Your headaches appear out of nowhere and are so severe that they routinely prevent you from completing daily tasks.
• Pain is impairing your quality of life and interrupting your work.
• Headaches have become more frequent and/or more severe over time.
• Without a history of headaches, you start getting them in your fifties or older. Late-onset headaches are less common and may indicate more serious health problems, Pepper says.
