Migraine or Tension?

The pill is already in your hand before you've named the pain.

Ibuprofen. Paracetamol. Something left over from a prescription you barely remember. You swallow it. You call it "a headache." You move on.

Most people do exactly this. And that single, careless word — headache — conceals one of the most common diagnostic failures in modern medicine.

For decades, doctors assumed they could tell migraine from tension headache at a glance. Many still assume this. The evidence tells a different story. A study spanning twelve countries found that only 28 percent of people living with migraine knew they had it.^[1] The rest called it stress, sinus trouble, or simply "a bad headache." An even more striking finding came from the American Migraine Study II: 94 percent of patients carrying a non-migraine diagnosis actually met the clinical criteria for migraine.^[2]

Peter Goadsby — professor of neurology at King's College London and UCLA, recipient of the 2021 Brain Prize for his pioneering migraine research — spent years confronting this gap. Before his team's breakthroughs, he observed, migraine was treated as a soft disorder, almost psychological — a problem of coping, not of biology.^[9] That perception left millions undertreated for a condition now recognized as the second most disabling disease on the planet.

A skeptic might still ask: does the label really matter? If the head hurts, doesn't any painkiller help?

No. And the price of that assumption is staggering. A 2024 study in Headache found that misdiagnosed migraine patients visited emergency rooms nearly twice as often and accumulated significantly higher healthcare costs across every care category — inpatient, outpatient, prescriptions — compared to those who received the correct diagnosis from the start.^[3] The average delay between first attack and correct diagnosis stretches to nearly eight years.^[4]

Eight years. Of swallowing the wrong pill. For the wrong pain.

Two words can begin to close that gap: migraine and tension. They feel different. They behave differently. And distinguishing them is simpler than most people expect.

Walk Up a Flight of Stairs

Here is one of the most reliable clinical clues in headache medicine — and you can test it yourself the next time your head hurts.

Climb a staircase. Or bend forward quickly.

Then listen to what your pain does.

Migraine punishes movement. The pain surges with each step, throbs harder with exertion, makes you grip the railing and regret the attempt. This is not a side effect of severe pain; the International Classification of Headache Disorders lists "aggravation by routine physical activity" as a formal diagnostic criterion for migraine.^[5] Neurologists use this distinction daily.

Tension headache does not behave this way. It sits there — dull, steady, unmoved by stairs. Some patients find that a brisk walk actually helps it ease.

One question — does movement make it worse? — separates these two conditions more reliably than most people realize.

What Each One Actually Feels Like

The differences extend well beyond the staircase.

Migraine pain pulses. It throbs in rhythm with the heartbeat, usually favoring one side of the head. And it rarely arrives alone. Nausea rolls in — sometimes tipping into vomiting. Light becomes so painful that an ordinary room feels like an interrogation. Sound amplifies until a normal conversation lands like a slap. About one in five patients experience aura beforehand: visual distortions, tingling, blind spots that crawl across the field of vision.^[5]

An untreated migraine attack lasts four to seventy-two hours. It can swallow an entire weekend.

Tension headache feels like a band tightening across both sides of the skull — forehead, temples, the back of the neck. The pain presses but does not pulse. No nausea. No aura. Light and noise may mildly annoy, but they do not send you retreating to a dark room with the curtains drawn. Up to 78 percent of the general population will experience a tension headache at some point.^[6] Most people work right through it.

The Grey Zone Is Real

Some readers will object that real life rarely sorts this neatly.

They would be right.

Research shows that 94 percent of migraine patients also experience tension-type headaches between attacks.^[7] The Spectrum Study found that nearly one-third of patients initially diagnosed with tension-type headache were later reclassified as migraine once researchers reviewed detailed headache diaries.^[8] A single episode can genuinely look like either condition.

A pattern over weeks cannot.

Did the pain worsen on the stairs? Was it one-sided? Did light bother you? Did you feel nauseous? Did the attack last longer than four hours?

No single answer proves a diagnosis. But five or six answers, repeated across several episodes, reveal the real story. This is precisely why headache diaries exist — and why neurologists say a diary is one of the most powerful diagnostic tools a patient can bring to their first appointment.^[11] Memory fails. Patterns on paper do not.

Why the Right Answer Changes Everything

Migraine and tension headache do not just feel different. They respond to fundamentally different treatments.

Triptans target the specific neurological pathways that drive a migraine attack. Taken early, they work remarkably well — and they do nothing whatsoever for tension headache.^[8] Meanwhile, the strategies that tension headache responds to — stress management, posture correction, muscular relaxation — rarely touch a migraine in full force.

The wrong treatment carries its own danger. Frequent use of painkillers for headaches that keep returning can trigger medication-overuse headache — a new pattern of daily pain layered on top of the original condition.^[5] A cycle harder to break than the problem that started it.

And this is not an edge case. Population-based data from Europe indicate that only 2 to 14 percent of people eligible for migraine prevention actually receive it.^[12] The gap between what medicine knows and what patients get remains, in the words of a European Headache Federation consensus statement, a substantial public health challenge.^[12]

Your Move

You do not need to diagnose yourself with clinical precision. You need to observe yourself honestly.

Next time your head hurts, notice five things: Throbbing or pressing? One side or both? Worse with movement? Light or sound intolerable? Nauseous?

Write them down. Every time.

In Migraine Companion, Mi helps you track exactly these details — building the kind of diary that transforms invisible patterns into a clear, shareable picture. Over weeks, the guessing fades. The pattern sharpens. And when the pattern is clear, the right treatment follows.

Because the question was never "do I have a headache?"
