A Migraine Is More Than a Headache
A migraine is a neurological condition causing severe pain, nausea, and sensory sensitivities following a predictable sequence of phases. Migraine affects roughly 1 in 7 people worldwide. Understanding each phase helps you recognize an attack and know when to act.
The Four Phases of a Migraine, and What Each One Feels Like
Not everyone experiences all four phases; many only have the headache phase. Understanding the full sequence explains why migraine feels like far more than just pain.
Phase 1: Prodrome (Up to 48 Hours Before the Headache)
The prodrome is a series of early warning signs. These signs can appear as early as two days before the headache. These signs include fatigue, excessive yawning, craving for certain foods, mood changes, stiff neck, thirst, and difficulty concentrating.
Phase 2: Aura (20-60 Minutes Before the Headache)
About 1 out of 3 people experience neurological symptoms due to a wave of electrical activity that occurs on the brain. This occurs over 5-20 minutes and resolves within one hour.
Visual aura is most common:
- Zigzag lines, arcs of flashing light, or shimmering waves
- Blind spots or areas of blurred vision that slowly expand
- Objects appearing distorted in size (Alice in Wonderland syndrome)
Other aura symptoms include tingling or numbness spreading up the arm and across the face, word-finding difficulties, and dizziness. Weakness on one side (hemiplegic migraine) is rare and requires medical evaluation. An aura lasting over an hour needs prompt attention.
Phase 3 The Headache Phase (4-72 Hours)
The pain is throbbing or pulsating, often described as feeling a heartbeat in the skull, and typically one-sided, around a temple, behind one eye, or across one side of the forehead. It ranges from moderate to severe and worsens with any physical movement.
Alongside the pain:
- Nausea, sometimes severe; vomiting in around a third of cases
- Photophobia, bright light, feels almost physically painful
- Phonophobia: ordinary sounds feel unbearable
- Sensitivity to smells (osmophobia)
- Pallor and a drained appearance
Lying still in a dark, quiet room is the typical response. Sleep is often the only way to end the attack.
Phase 4 Postdrome (“The Migraine Hangover”)
Once the headache fades, the postdrome phase brings up to 48 hours of exhaustion, brain fog, lingering sensory sensitivity, low mood, and a dull residual ache where the pain was. Some people feel a brief surge of energy or euphoria instead.
Migraine With Aura vs Migraine Without Aura: How They Differ
Migraine without aura comprises 70 to 75 percent of all headaches that occur without any preceding warning signs. Migraine with aura, as opposed to migraine without aura, has preceding neurological signs, and this form has a slightly higher risk for causing stroke, particularly in people who smoke and/or use combined hormonal contraception. Silent migraine (aura without headache) produces warning symptoms but no pain, and is most common in people over 50, sometimes mistaken for a TIA.
How Is a Migraine Different from a Tension Headache or Cluster Headache?
Tension Headache
A band of dull, steady pressure that affects the entire head. It is not throbbing, does not increase with movement, and does not include nausea or sensitivity to light.
Cluster Headache
Severe, sharp pain on one side of the head, around one eye, occurs in clusters over days or weeks, wakes the patient from sleep, and may include tearing, reddening of the eye, and stuffiness on the affected side.
Migraine
Distinguished by throbbing one-sided pain that worsens with movement, alongside nausea and sensory sensitivities. Far more disabling and long-lasting than a tension headache.
Warning Signs That Are Not a Migraine: When to Seek Urgent Help
Some headache features require immediate attention and must not be assumed to be migraine:
- A sudden, extremely severe “thunderclap” headache may indicate a subarachnoid hemorrhage; call 911 immediately
- Headache with fever, stiff neck, and a rash, possible meningitis
- Headache following a head injury
- Confusion, one-sided weakness, face drooping, or speech problems possible stroke
- Aura symptoms lasting longer than an hour
Call 911 or go to the nearest ER without delay.
Conclusion
Taking care of a migraine means taking care of the entire body, from the initial signs of the migraine, or the prodrome, all the way through the after-effects, or the postdrome. Because the experience of a migraine is unique, with or without the presence of the aura, the best way to take control of your migraine is to understand your unique triggers. Although the pain of the migraine gets the most attention, understanding the entire process of the migraine experience can help you take care of your migraine more effectively. If your symptoms have changed or if your migraine has had a sudden, intense onset, or a "thunderclap," you should seek medical care immediately.
