Migraine

When to Call A Doctor

If you have a history of migraine, you should contact your doctor if you develop headaches that differ from your usual headache or other migraine symptoms. Examples include:

• Headaches that get worse over time

• New onset of migraine in a person over age 40

• Severe headaches that start suddenly (often known as thunderclap headaches)

• Headaches that worsen with exercise, sexual intercourse, coughing or sneezing

• Headaches with unusual symptoms such as passing out, loss of vision, or difficulty walking or speaking

• Headaches that start after a head injury

In addition, you may want to see your health care professional if you have headaches that do not get better with over-the-counter medications; severe headaches that interrupt work or the enjoyment of daily activities; or daily headaches.
