Migraine in India: when 'sinus' is really a brain event

Roughly one in four Indians lives with migraine — and most do not know that is what they have. The pain sits over the forehead and cheeks, the nose feels blocked, so a chemist or a GP calls it 'sinus.' Others are told it is 'just tension,' or stress, or a woman being dramatic. On average it takes five to seven years to get the right name for it.

This matters because migraine is not an ordinary headache you push through. It is a specific, stereotyped brain event — a storm in a nerve-and-chemical system that scans cannot see and willpower cannot stop. Treating it as 'sinus' means years of the wrong drops, and treating it with daily painkillers can quietly make it far worse.

This page explains what migraine actually is, why so much of it is misread as sinusitis, which triggers are real and which are myth, and what genuinely helps.

Migraine vs headache

A headache is a symptom. Migraine is a whole brain event that includes the headache plus nausea, light and sound sensitivity, and often a warning and a recovery phase. Calling migraine 'a headache' is like calling a thunderstorm 'some rain.'

The four phases

Many attacks run through stages: a prodrome hours to days before (mood change, yawning, sweet cravings, neck stiffness); for some, an aura; the headache itself; and a postdrome — the 'migraine hangover' of fatigue and fog.

Aura

Reversible nerve symptoms that come before or with the pain in about one in three migraineurs — usually zig-zag lights or blind spots, sometimes numbness spreading up an arm. It is a slow wave crossing the brain's surface, and it fades within an hour.

Trigeminovascular system

The nerve-and-blood-vessel network around the brain's covering that generates migraine pain when it is switched on.

CGRP

A messenger chemical the trigeminal nerve releases during an attack. It drives the inflammation and pain — and blocking it is the biggest advance in migraine treatment in thirty years.

Medication overuse headache

The trap: taking acute painkillers too often — more than about 10–15 days a month — can turn occasional migraine into a daily headache.

A migraine attack is not random pain. It is an ordered sequence in an over-excitable brain. Here is what unfolds.

Notice what is missing: blocked sinuses. The watery nose and facial pressure are the nerve storm spilling over — which is exactly why 'sinus' treatment keeps failing.

The most useful numbers here separate migraine from the things it gets confused with.

How big this is in India

• About 25% of adults have migraine — roughly 32% of women and 18% of men.
• It is more common in rural India (29%) than in cities (22%).
• It takes 5–7 years on average to diagnose correctly, and an estimated 40–60% are first mislabelled as sinusitis.
• Worldwide, migraine is the second-leading cause of years lived with disability — and the first among young women.

The telltrue sinusitis brings fever and thick, coloured discharge and lasts for days. A throbbing 'sinus' headache that comes with nausea, hates light, and clears in a day is almost always migraine.

Myth 1 — It's sinus.

Most recurrent 'sinus headaches' in India are migraine. True sinusitis brings fever and thick discharge and lasts days; a throbbing headache with nausea that clears in a day is migraine wearing a sinus mask.

Myth 2 — Chocolate and MSG cause migraine.

Mostly myth. The chocolate craving is part of the warning phase — you crave it because an attack is already coming. Controlled trials clear MSG for most people. Blaming food misses the real triggers.

Myth 3 — Migraine is just stress.

Stress is one trigger among many, and the classic one is the let-down after stress — the 'weekend migraine.' But the disease itself is biological, not a weak mind.

Myth 4 — It's a women's problem.

Men get migraine too; they are simply diagnosed less. It is nearly twice as common in women because of hormones, but not theirs alone.

Myth 5 — Daily painkillers are a safe fix.

The most important warning here. Taking acute painkillers more than 10–15 days a month can turn episodic migraine into a daily headache. The cure becomes the cause.

Myth 6 — Migraine isn't a real disability.

Globally it is the top cause of disability in young women. A severe attack can erase a working day.

Myth 7 — The new CGRP injections are a cure.

They are an excellent preventive, not a cure. They roughly halve attacks for about half of patients, cost a lot, and usually must be continued.

Not push through, and not panic. A short, ordered set of moves around the real mechanism.

See a doctor urgently ifa headache hits maximum severity in seconds, comes with fever and a stiff neck, follows a head injury, brings weakness, confusion or lasting vision loss, or is a brand-new daily headache after 50 — these are not ordinary migraine.

Follow one believable arc — it explains the disease better than any scan.

The label. Priya, 31, works at a Hyderabad call centre. Every few weeks a throbbing pain takes over one side of her head, with nausea and a hatred of light. Because it sits over her cheek and her nose feels blocked, three doctors call it 'sinus.' She buys sinus drops and a painkiller strip, they take the edge off — so she believes it.

The trap closes. The attacks come more often. She now takes a painkiller most days, sometimes two. Far from helping, the daily pills have tipped her into a near-constant headache — a medication-overuse headache layered on the migraine she was never told she had.

The real name. A neurologist takes ten minutes of history — one-sided, throbbing, nausea, light, no fever, never any thick discharge — and names it: migraine, misread as sinus for years. The fix starts by stopping the daily painkillers, not adding more.

The turn. She steadies her sleep, stops skipping meals on shift, caps acute medicine to a few days a month, and starts a preventive. The daily headache lifts. The migraines, when they come, are fewer and treatable.

That is the lesson in one life. The diagnosis was hiding in plain sight, and the 'cure' she trusted was deepening the problem.

Step back and migraine is one of the strangest blind spots in Indian health: a condition that affects a quarter of the population, ranks among the world's leading causes of disability, and is still routinely waved away as 'sinus' or 'tension.' The science is no longer uncertain — migraine is a brain event driven by a nerve chemical called CGRP, as real and physical as asthma or epilepsy.

Why this matters is the gap between that biology and the folklore. A five-to-seven-year delay to diagnosis is years of the wrong drops, missed work, and the quiet self-blame of people told their disabling pain is stress or drama. And the most common 'treatment' — a daily painkiller from the chemist — is itself a leading cause of the chronic daily headache it is meant to relieve.

The lesson is the one that keeps returning in Indian medicine: the story we tell about a symptom decides how we treat it. Call it sinus, and you reach for the wrong drops for a decade. Call it migraine, and a whole toolkit — trigger control, smarter acute use, modern prevention — opens up.

The long-term shift is to take head pain seriously instead of normalising it. A throbbing, sickening, light-hating headache is not a character flaw or a sinus quirk. It is a treatable brain condition — and naming it correctly is the first dose of the cure.
