Migraine vs Headache: How to Tell the Difference

Migraine Is a Neurological Condition, Not Just a Bad Headache

A tension headache — by far the most common type — usually feels like a dull, steady pressure or tightness on both sides of the head, often described as a band squeezing around the skull. It's uncomfortable but typically doesn't stop most people from going about their day, and it responds well to over-the-counter pain relievers, water, and rest.

Migraine is different at a mechanistic level. It's considered a neurological disorder involving changes in brain activity, blood vessel behavior, and nerve signaling, not simply "a headache that's worse." That distinction matters because it explains why migraine comes with a wider cluster of symptoms beyond pain, and why it often needs migraine-specific treatment rather than just a stronger painkiller.

How to Tell Them Apart in the Moment

Location and quality of pain is often the first clue. Tension headaches tend to be dull, constant, and on both sides. Migraine pain is more often throbbing or pulsing, and frequently, though not always, concentrated on one side of the head.

What Migraine Aura Actually Looks Like

Roughly 15 to 20 percent of people with migraine experience an aura — a set of neurological symptoms that shows up before or alongside the headache phase. Visual aura is the most common form: shimmering zigzag lines, blind spots, or flashing lights that spread gradually across part of the visual field over 10 to 30 minutes.

Aura can also show up as tingling or numbness that spreads from the hand up the arm, temporary difficulty finding words, or, less commonly, mild weakness on one side of the body. These symptoms are temporary and typically resolve within an hour, but new or unusual neurological symptoms — especially if they're a first-time occurrence — are worth mentioning to a doctor to rule out other causes.

Light sensitivity and the urge to rest in a dark, quiet room are hallmark migraine symptoms that tension headaches rarely produce.

What Sets Off Each One

Tension headaches are most often triggered by stress, poor posture, eye strain from screens, dehydration, or skipped meals — generally things tied to the day's physical or mental load, and they usually resolve once the underlying cause is addressed.

Migraine triggers are more individualized and can include hormonal fluctuations (many women notice a pattern around their menstrual cycle), certain foods and drinks like aged cheese, alcohol, or excess caffeine, changes in sleep patterns in either direction, strong smells, bright or flickering light, and weather or barometric pressure shifts. Keeping a simple headache diary for a few weeks — noting food, sleep, stress, and cycle timing — is one of the most useful things you can bring to a doctor's appointment.

Why the Right Treatment Depends on Which One You Have

Tension headaches typically respond well to standard over-the-counter pain relievers like ibuprofen or acetaminophen, along with hydration, stretching, and stress management. For frequent tension headaches, addressing the root cause — posture, screen habits, sleep — often does more than medication alone.

Migraine treatment splits into two categories: abortive treatments taken during an attack to stop it (triptans, certain anti-nausea medications, and newer options like CGRP-targeting drugs), and preventive treatments taken regularly to reduce how often attacks happen (beta-blockers, certain antidepressants, and newer monthly or quarterly CGRP-inhibitor injections). A doctor typically considers preventive treatment once migraines happen four or more days a month or significantly disrupt daily life.

Red Flags Worth Getting Evaluated

Most headaches, including most migraines, aren't emergencies. But certain patterns warrant a prompt medical evaluation: a headache that's sudden and severe, unlike any you've had before; a headache that starts after age 50 for the first time; one accompanied by fever, stiff neck, confusion, vision changes, or weakness; or a pattern that's steadily worsening over days or weeks rather than coming and going.

If migraines are frequent enough to interfere with work, school, or relationships, that's also worth raising with a doctor even without red-flag symptoms — effective preventive treatments exist, and many people go years assuming nothing can be done before learning otherwise.

Managing Migraine Between Attacks

Beyond medication, the day-to-day habits that reduce migraine frequency for many people are consistent and unglamorous: regular sleep and wake times (even on weekends), steady meal timing rather than skipping meals, staying hydrated, and moderating caffeine rather than cutting it entirely, since sudden caffeine withdrawal is itself a common trigger.

Exercise has a slightly complicated relationship with migraine — intense, sudden exertion can trigger an attack in some people, but regular, moderate aerobic exercise is associated with fewer migraine days over time in multiple studies. Starting gradually and staying well hydrated during exercise tends to reduce the risk of it backfiring.

Stress doesn't just trigger attacks during stressful periods — many people notice migraines hitting during the drop in stress right after a demanding week, sometimes called "weekend migraines." Gradual wind-down routines rather than an abrupt shift from high stress to full rest can help smooth that transition out.

What to Expect From a Doctor's Visit

Migraine is typically diagnosed based on your symptom history and pattern rather than a specific test, using established diagnostic criteria that look at how many attacks you've had, how long they last, and which associated symptoms show up alongside the pain. Bringing a headache diary with dates, duration, symptoms, and possible triggers makes this conversation much faster and more useful.

Imaging like an MRI or CT scan isn't usually needed for typical migraine, but a doctor may order it if your headache pattern is unusual, started suddenly, changed significantly, or comes with any of the red-flag symptoms mentioned above — mainly to rule out other causes, not because migraine itself shows up on a scan.

It's also worth naming a common source of confusion up front: many people who describe their headaches as "sinus headaches" actually have migraine, since migraine can cause facial pressure and nasal congestion that mimics sinus symptoms. Studies looking at people diagnosed with sinus headache have repeatedly found that a large share meet the criteria for migraine instead once formally evaluated.
