Why your head hurts: Q&A with a headache specialist


Headache is one of the world’s most common health issues. Some 40 million Americans suffer from headaches, but that suffering is often misunderstood.

Because pain is subjective, it’s hard for people who do not suffer headaches to appreciate the severity and the relentlessness. Plus, there’s a stigma attached to headache complaints. But headaches, and migraine headaches in particular, reduce quality of life, prevent full participation in work and activities, and even alter mood. Migraine is the most common disabling brain disorder.

Headache specialists, such as internist Chantel Strachan, MD, are part of initiatives to educate more primary care physicians on headache and migraine. Strachan, who completed a fellowship in headache and facial pain, shared the basics with us.

What is a headache?

Headaches happen when an unknown mechanism activates nerves in your body that send pain signals to the brain. This mechanism is activated by a variety of factors including stress, sleep deprivation, hunger, alcohol, computer screens, and teeth grinding, to name a few.

A headache can be its own medical condition, and a headache can be a symptom of something else, including:

  • Dehydration
  • Medication side effect
  • Medication overuse
  • High blood pressure
  • Sinus congestion
  • Tumor
  • Migraine

Migraine is not the name of a type of headache. It’s a neurological disease that causes recurrent, debilitating headaches and other symptoms, such as nausea and sensitivity to light and/or sound, and each episode can last for weeks.

How do I get rid of a headache?

The most common type of head pain is a tension headache, which can be caused by physical and emotional stress, anxiety, or head injury. Tension headaches are usually treatable with acetaminophen (Tylenol) or ibuprofen (Advil).

Some people need stronger medication, such as Excedrin migraine or other over-the-counter drugs with added caffeine, and sometimes prescription medication.

Many people get relief from massage, acupuncture, and eating fresh, healthier foods.

When should I see a doctor about headaches?

If a headache does not go away within three days with any of these methods, contact your doctor. It may be a sign something more than a headache is going on.

When should I go to the ER with a headache?

If a headache is not responsive to over-the-counter medications—and is so severe that it’s an obstacle to any activity for a few hours—contact a doctor or go to the ER.

If you or someone around you has a headache, watch for other symptoms, such as vision changes, weakness on one side of face or body, confusion, or changes in walking.

If you notice any of these or other unusual or severe symptoms, contact a doctor immediately or go to an emergency room.

What is migraine?

Migraine is a neurological disease that causes a variety of symptoms, including headache. Migraine attacks happen when nerves in and near blood vessels are activated and send pain signals to your brain.

The cardinal symptoms of a migraine are intense throbbing headache, typically on one side of your head, and the following:

  • sensitivity to light and/or sound
  • blurry vision
  • dizziness
  • stomach upset, including nausea, vomiting, and loss of appetite

Migraine phases

Migraine has four phases. Not every person who suffers migraine experiences all four phases, and each attack can be different. Some symptoms can occur across more than one phase.

The whole migraine attack process can take weeks.

In the past decade, after more was discovered about the biochemistry of migraines, new medications have become available for treatment and prevention of migraine. Many medications are directed at reducing the amount of CGRP—calcitonin gene-related peptide—which has a role in pain in the brain and nervous system. Discuss with your doctor if these are good treatment options.

Should I go to a headache specialist or a neurologist if I suffer headaches?

If your headache doesn’t warrant a trip straight to the emergency room (again, watch for unusual symptoms, such as changes in mobility), go to a primary care physician first, ideally someone who specializes in headache. A primary care physician can determine if something else is going on, such as high blood pressure, anemia, or depression. A primary care physician is trained to look at the big picture, not just focus on the headache.

Neurologists are great, and you may need one, but don’t self-diagnose. Let another doctor refer you to the right specialist.
