What Is a Migraine Headache?

Q:
What is a migraine headache?

A:
Migraine headache is a result of specific changes within the brain. It causes severe head pain that is often accompanied by sensitivity to light, sound, or smells.

Common symptoms include:

  • Eye pain
  • Sensitivity to light or sound
  • Nausea
  • Vomiting
  • Severe pain, usually on one side of the head that some individuals describe as “pounding”

Not all headaches represent migraines, and migraine is not the only condition that can cause severe and debilitating headaches.

For example, cluster headaches are very severe headaches that affect one side of the head in a recurrent manner (occurring in a “cluster” over time). The pain is sometimes described as “drilling,” and can be worse than migraine pain in some cases. Cluster headaches are less common than migraine.

Tension headaches are a more common cause of headache. These occur due to contraction of the muscles of the scalp, face, and neck.

Remember, you should always make an appointment if your headaches are frequent or last more than a few days.
