What is a migraine?

A migraine is a severe headache that causes throbbing, pulsing head pain on one side of your head. The headache phase of a migraine usually lasts at least four hours, but it can also last for days. This headache gets worse with:
  • Physical activity.
  • Bright lights.
  • Loud noises.
  • Strong odors.

Symptoms

Migraines, which affect children and teenagers as well as adults, can progress through four stages: prodrome, aura, attack and post-drome. Not everyone who has migraines goes through all stages.

Prodrome

One or two days before a migraine, you might notice subtle changes that warn of an upcoming migraine, including:
  • Constipation
  • Mood changes, from depression to euphoria.
  • Food cravings
  • Blurred vision.
  • Neck stiffness.
  • Increased urination.
  • Fluid retention.
  • Frequent yawning.
  • Aura
For some people, an aura might occur before or during migraines. Auras are reversible symptoms of the nervous system. They’re usually visual but can also include other disturbances. Each symptom usually begins gradually, builds up over several minutes and can last up to 60 minutes.

Examples of migraine auras include:

  • Visual phenomena, such as seeing various shapes, bright spots or flashes of light.
  • Vision loss.
  • Pins and needles sensations in an arm or leg.
  • Weakness or numbness in the face or one side of the body.
  • Difficulty speaking.
  • Attack
A migraine usually lasts from 4 to 72 hours if untreated. How often migraines occur varies from person to person. Migraines might occur rarely or strike several times a month.
During a migraine, you might have:
  • Pain usually on one side of your head, but often on both sides.
  • Pain that throbs or pulses.
  • Sensitivity to light, sound, and sometimes smell and touch.
  • Nausea and vomiting.
  • Post-drome
After a migraine attack, you might feel drained, confused and washed out for up to a day. Some people report feeling elated. Sudden head movement might bring on the pain again briefly.

Causes

Though migraine causes aren’t fully understood, genetics and environmental factors appear to play a role. Changes in the brainstem and its interactions with the trigeminal nerve, a major pain pathway, might be involved. So might imbalances in brain chemicals — including serotonin, which helps regulate pain in your nervous system.
Migraine triggers
There are a number of migraine triggers, including:
  • Hormonal changes in women. Fluctuations in estrogen, such as before or during menstrual periods, pregnancy and menopause, seem to trigger headaches in many women.
  • Hormonal medications such as oral contraceptives, also can worsen migraines. Some women, however, find that their migraines occur less often when taking these medications.
  • Drinks. These include alcohol, especially wine, and too much caffeine, such as coffee. Stress. Stress at work or home can cause migraines.
  • Sensory stimuli. Bright or flashing lights can induce migraines, as can loud sounds. Strong smells — such as perfume, paint thinner, second hand smoke and others — trigger migraines in some people.
  • Sleep changes. Missing sleep or getting too much sleep can trigger migraines in some people.
  • Physical strain. Intense physical exertion, including sexual activity, might provoke migraines.
  • Weather changes.
    • A change of weather or barometric pressure can prompt a migraine. Medications. Oral contraceptives and vasodilators, such as nitroglycerin, can aggravate migraines.
  • Foods. Aged cheeses and salty and processed foods might trigger migraines. So might skipping meals.
  • Food additives. These include the sweetener aspartame and the preservative monosodium glutamate (MSG), found in many foods.

Risk factors

Several factors make you more prone to having migraines, including:
  • Family history. If you have a family member with migraines, then you have a good chance of developing them too.
  • Age. Migraines can begin at any age, though the first often occurs during adolescence. Migraines tend to peak during your 30s, and gradually become less severe and less frequent in the following decades.
  • Sex. Women are three times more likely than men to have migraines.
  • Hormonal changes. For women who have migraines, headaches might begin just before or shortly after onset of menstruation. They might also change during pregnancy or menopause. Migraines generally improve after menopause.

Complications

Taking painkillers too often can trigger serious medication-overuse headaches. The risk seems to be highest with aspirin, acetaminophen (Tylenol, others) and caffeine combinations. Overuse headaches may also occur if you take aspirin or ibuprofen (Advil, Motrin IB, others) for more than 14 days a month or triptans, sumatriptan (Imitrex, Tosymra) or rizatriptan (Maxalt) for more than nine days a month.
Medication-overuse headaches occur when medications stop relieving pain and begin to cause headaches. You then use more pain medication, which continues the cycle.
