What Is a Migraine?

"Isn't it just a bad headache?" If you've ever had to cancel a day because of one, you already know the answer — no, it really isn't. A migraine is a neurological condition that produces attacks, not just head pain. The short animation above, "Migraine Pathophysiology" (about a minute and a half), sums up the core pattern the way clinicians describe it: a headache that is usually throbbing and often one-sided, arriving with nausea and a sensitivity to light and sound, and made worse by moving your head. That cluster — pain plus whole-body symptoms — is what sets migraine apart, and the questions below walk through it in the order most people ask them.

What does an attack actually feel like?

It tends to build rather than strike all at once. The pain is often described as pounding or throbbing, frequently on one side of the head, and ordinary activity — climbing stairs, bending down, even walking across the room — can make it throb harder, which is why so many people end up lying still in a dark, quiet room. Alongside the pain you might feel sick to your stomach, struggle with bright light or normal conversation volume, and find concentrating almost impossible. Some people notice warning signs hours beforehand, such as yawning, food cravings, neck stiffness or a dip in mood. An untreated attack commonly lasts hours and can stretch into a couple of days before it fully clears, often leaving a washed-out, "hungover" feeling behind it. If dizziness is a big part of your attacks, it is also worth reading about what vertigo is and how it differs, because the two can overlap.

What is an aura — and does everyone get one?

No, not everyone. An aura is a set of temporary neurological symptoms that typically arrive before or alongside the pain. The most familiar kind is visual: flashing lights, zigzag lines, shimmering edges, or a patch of vision that briefly disappears. Others notice tingling that creeps up a hand toward the face, or a short-lived difficulty finding words. Aura symptoms usually develop gradually and pass within about an hour. They can be frightening the first time — especially because they can resemble the warning signs of a stroke — so a first-ever aura, or one that behaves differently from your usual pattern, deserves prompt medical assessment rather than self-diagnosis.

What sets an attack off?

Triggers vary a lot from person to person, which is why a simple headache diary — noting sleep, meals, stress and the timing of attacks — often reveals more than any generic list. Commonly reported triggers include missed meals, too little or even too much sleep, the let-down after a stressful period, hormonal changes around periods, bright or flickering light, strong smells, and changes in the weather. Alcohol and certain foods get blamed often, though sometimes the "trigger" is actually an early symptom: craving a particular food can be part of the warning phase rather than the cause. The practical goal isn't to avoid everything forever — that's neither possible nor healthy — but to spot your own repeat offenders and steady the basics: regular sleep, regular meals, and not letting a busy day erase both lunch and water.

How is migraine diagnosed and treated?

There's no single scan or blood test that proves migraine. Diagnosis is mainly a careful history: where the pain sits, how it behaves, what comes with it, how long attacks last, and what runs in the family — migraine often does. A physical and neurological examination supports that picture, and scans are usually reserved for headaches that look unusual or change character. Treatment then works on two levels. During an attack, the aim is to ease pain and nausea early, rest in a dark quiet space, and use the pain relief your clinician has advised for you. If attacks are frequent or disabling, your clinician may discuss preventive treatment taken regularly to reduce how often they come — the right choice depends on your other health conditions and medicines, so this article won't name drugs or doses. Do seek urgent care for a headache that is sudden and maximal ("the worst ever"), follows a head injury, or comes with weakness, confusion, fainting, fever with a stiff neck, or vision loss — those are not symptoms to wait out at home.

Frequently Asked Questions

Is a migraine just a severe headache?
No. Headache is only one part of an attack. Migraine typically adds nausea, sensitivity to light and sound, and pain that worsens with movement — and some people also experience aura symptoms such as flashing lights or tingling before the pain starts.

How long does a migraine attack last?
An untreated attack commonly lasts several hours and can stretch into a couple of days, sometimes followed by a day of feeling drained. If an attack lasts much longer than your usual pattern, or doesn't respond to what normally helps, seek medical advice.

Should I get a brain scan for migraine?
Not usually. Migraine is normally diagnosed from the history of your attacks and a neurological examination. Scans are generally reserved for headaches with unusual features, a changing pattern, or warning signs — your clinician will advise if one is needed in your case.

Can children get migraines?
Yes. Migraine occurs in children as well as adults, though attacks in children can be shorter and may feature stomach symptoms more prominently than head pain. A child with repeated severe headaches should be assessed by a clinician.
