Have you ever experienced this: you went to the doctor and said you had a "migraine," only for the doctor to finish the consultation and say, "This isn’t a migraine"?
What exactly is a real migraine? And why is it different from what we imagine?
The Name "Migraine" is Actually Quite Misleading
Many people tell doctors in clinics, "I have a migraine—my head hurts on the right (or left) side."
Sounds reasonable, right? Since ‘Migraine’ in Chinese literally means ‘one-sided headache,’ shouldn’t it be a one-sided headache?
The probability of a migraine being on one side is only about 60%—at best, just a bit more than half.
Migraine pain can occur on both sides, at the back of the head, or even constantly change locations.
Some people clearly feel pain right in the middle but are diagnosed with migraines, making them think, "Did the doctor make a mistake?" This is truly a huge misunderstanding.
Migraine is a "Disease Name," Not a "Symptom Description"
The Taiwan Headache Society used a great analogy: just as the "White House" does not refer to just any white palace, but specifically to the office of the President of the United States;
Migraine is a formal diagnostic name for a specific disease, and it has no necessary connection to having a headache on only one side.
Migraine is a neurological disease that has a clear set of diagnostic criteria established by the International Headache Society.
Unilateral headache is just one of the possible features, not the sole basis for judgment.
So, What Does a Real Migraine Actually Look Like?
Since we cannot judge solely by "which side hurts," how can you know if you have a migraine?
According to the diagnostic criteria of the International Classification of Headache Disorders, 3rd edition (ICHD-3), a migraine must meet the following conditions:
| Condition | Description |
|---|---|
| Attacks | At least 5 attacks fulfilling the following characteristics |
| Duration | Lasting 4 to 72 hours (when untreated or unsuccessfully treated) |
| Pain Characteristics (at least 2) | Unilateral location, pulsating quality, moderate or severe pain intensity, aggravation by or causing avoidance of routine physical activity |
| Associated Symptoms (at least 1) | Nausea and/or vomiting, photophobia (sensitivity to light) and phonophobia (sensitivity to sound) |
Common Experiences During a Migraine Attack
During a migraine attack, you might experience:
| Symptom | Description |
|---|---|
| Pulsating Throbbing Pain | Pulsating, throbbing pain like a heartbeat, throbbing one beat at a time with your pulse |
| Nausea and Vomiting | Even actual vomiting in severe cases |
| Photophobia and Phonophobia | Normal light and sound will make you even more uncomfortable |
| Pain Aggravated by Activity | Walking or climbing stairs makes the headache worse, making you want to just lie quietly in a dark room |
Furthermore, this pain can last from several hours to several days once it starts, severely affecting daily routines and work.
Some People Also Experience "Aura"
About 10% to 20% of migraine sufferers experience neurological warning signals before the headache starts:
- Flashing spots of light or wavy shadows in the field of vision
- Feeling numbness or weakness on one side of the body
- Sudden slurred speech or difficulty speaking
These aura symptoms usually develop over 20 to 30 minutes, followed closely by the onset of the headache.
If It’s Not a Migraine, What is My Usual Headache?
After hearing the description of migraine, you might think: "So what’s going on when I get a headache from stress or poor sleep?"
The vast majority of headaches we encounter in daily life are tension headaches (also known as tension-type headaches).
Various studies show that 30% to 78% of the general population will experience at least one tension headache in their lifetime.
Migraine vs. Tension Headache
These two types of headaches are often confused, but the differences are quite distinct:
| Comparison | Migraine | Tension Headache |
|---|---|---|
| Pain Sensation | Pulsating throbbing pain (throbbing like a heartbeat) | Tightness, pressure (like a band squeezing the head) |
| Pain Location | Unilateral or bilateral, may shift | Usually both sides of the head, forehead, or back of the head |
| Severity | Moderate to severe | Mild to moderate |
| Duration | 4 to 72 hours | 30 minutes to several days |
| Nausea/Vomiting | Common | Rare |
| Sensitivity to Light/Sound | Common | Rare |
| Physical Activity | Aggravated by physical activity | Usually unaffected or slightly relieved by activity |
Tension headaches are mostly related to stress, fatigue, poor posture, or muscle tension. Resting a bit and relaxing your neck and shoulders usually helps.
In comparison, migraines present much stronger pain, come with more symptoms, and have a greater impact on life.
Why Do We Need to Distinguish Between Headache Types?
You might think: "I’ll just take painkillers for a headache anyway, why bother telling them apart?"
This line of thinking is actually quite dangerous.
The Treatments Are Completely Different
| Headache Type | Common Treatments |
|---|---|
| Tension Headache | General pain relievers (like Acetaminophen, Ibuprofen), muscle relaxants, lifestyle adjustments |
| Migraine | May require specific Triptans, and severe cases might need CGRP inhibitors or preventive treatment |
Migraine has its own exclusive treatments and strategies, which are vastly different from how general headaches are managed.
If you treat a migraine as a common headache, the results will likely be poor, and it will keep recurring.
Overusing Painkillers Makes It Worse
Overusing pain relievers long-term can actually trigger "medication overuse headaches", making headaches more frequent and harder to treat.
Among chronic migraine sufferers, many unknowingly develop a dependency on painkillers, falling into a vicious cycle of "the more they hurt, the more they take, and the more they take, the more they hurt."
Long-term Risks of Ignoring Migraines
If you suffer from migraines and continue to ignore them without proper management:
Migrainecan progress from occasional attacks to chronic migraine (headaches occurring 15 or more days per month for more than 3 months)- Long-term migraine sufferers face a higher risk of depression and anxiety
Migraineis also one of the top three causes of workplace productivity loss worldwide
Don’t Let the Name "Migraine" Fool You Anymore
Next time you get a headache, why not take a few seconds to observe:
Is it a dull tightness, or is it throbbing along with your heartbeat? Do you feel nauseous? Is the light exceptionally glaring?
These tiny details can help you understand your headache better and provide the doctor with more precise clues when you seek medical care.
If your headaches are frequent enough to affect your life, please don’t just endure it with painkillers. Consult a specialist in neurology for a proper diagnosis. Identifying the exact type of headache is the only way to treat it effectively and free yourself from its grip.
