The single biggest difference is that a migraine is a neurological event with whole-body symptoms, while a typical headache is just pain in your head. If your headache comes with nausea, sensitivity to light or sound, visual disturbances, or gets noticeably worse when you bend over or climb stairs, you’re likely dealing with a migraine rather than an ordinary headache. Understanding the specific differences can help you recognize what’s happening and respond appropriately.
Where and How the Pain Feels
A tension-type headache, the most common kind, usually feels like a band of pressure or tightness around both sides of your head. It’s uncomfortable but generally steady and dull. You can typically push through your day without much trouble.
Migraine pain is different in character. It tends to throb or pulse, often on one side of the head, though it can affect both sides. The intensity ranges from moderate to severe, and one of the hallmark features is that routine physical activity makes it worse. Walking up a flight of stairs, bending down to pick something up, or even just moving around the house can ramp up the pain. This aggravation with movement is actually part of the formal diagnostic criteria for migraine. People with tension headaches don’t typically experience this.
Symptoms Beyond the Pain
This is where the distinction becomes clearest. A tension headache is essentially just head pain. A migraine brings a constellation of neurological symptoms along with it.
Nausea is the most common and most bothersome companion symptom, reported by roughly 62% of people with migraine. Sound sensitivity follows, then vomiting. Light sensitivity, while extremely common during attacks, often ranks lower as the “most bothersome” symptom simply because it’s easier to manage by dimming lights or closing your eyes. Sensitivity to smells is also common. None of these symptoms are typical of a tension headache.
Some people also experience cognitive changes during a migraine: difficulty finding words, trouble concentrating, or a general feeling of mental fog. These can start before the pain itself arrives and linger after it fades.
Aura: A Warning Signal Unique to Migraine
About 25 to 30% of people with migraine experience aura, a set of temporary neurological symptoms that typically appear within the hour before headache pain begins. Aura symptoms usually last less than 60 minutes, though they can sometimes overlap with the pain phase.
Visual aura is the most recognizable form. You might see zigzag lines that slowly drift across your visual field, shimmering spots, flashes of light, or blind spots sometimes outlined by a circle or arc shape. These visual changes are distinct from the ordinary blurriness you might get from eye strain.
Aura isn’t always visual, though. Some people feel tingling that starts in one hand and slowly spreads up the arm, or numbness on one side of the face. Others have temporary difficulty speaking or finding the right words. In rarer cases, aura involves muscle weakness or hearing changes like ringing in the ears. If you’ve never experienced aura before and suddenly develop these symptoms, it’s worth getting evaluated promptly, since some of these signs can mimic a stroke.
Duration and Attack Pattern
Tension headaches can last anywhere from 30 minutes to several days, but they tend to come and go without a predictable pattern. Many people get them occasionally after a stressful day, poor sleep, or long hours at a screen.
An untreated migraine attack typically lasts between 4 and 72 hours. That’s a wide range, and where you fall depends on your triggers, the type of migraine you have, and whether you treat it early. If a migraine stretches beyond 72 hours without responding to treatment, it’s classified as status migrainosus, a prolonged attack that generally warrants medical attention.
Migraines also tend to follow a more structured progression. Many people notice a prodrome phase hours or even a day before the pain, marked by food cravings, mood changes, frequent yawning, neck stiffness, or fatigue. After the headache resolves, there’s often a postdrome or “migraine hangover” that can leave you feeling drained, foggy, or unusually sensitive for another day. Tension headaches don’t have this multi-phase architecture.
What’s Happening in Your Brain
A tension headache primarily involves the muscles and soft tissues around your head and neck tightening up. It’s mechanical and relatively straightforward.
A migraine is a fundamentally different process. It originates from a state of altered excitability in the brain itself, one that activates a pain network involving the nerves that wrap around the blood vessels in your brain’s outer lining. In people who are genetically susceptible, this system fires when it shouldn’t, releasing inflammatory signals that irritate those nerves and trigger pain.
For people who experience aura, there’s an additional step: a slow wave of electrical activity rolls across the brain’s surface at a few millimeters per minute, temporarily disrupting normal function in its path. This wave is what produces the visual distortions, tingling, or speech difficulties. As it passes, it releases a cascade of molecules that further activate pain-sensing nerves. This is why aura usually precedes or overlaps with the headache itself.
The throbbing quality of migraine pain comes from the sensitization of these nerve fibers. Once they’re activated, each pulse of blood through nearby vessels registers as a beat of pain. As the attack continues, even the nerves in your scalp and face can become sensitized, which is why touching your head, wearing a ponytail, or resting your face on a pillow can feel painful during a migraine. This widespread tenderness, called allodynia, doesn’t happen with tension headaches.
A Quick Comparison
- Pain quality: Tension headaches feel like pressure or tightness. Migraines throb or pulse.
- Location: Tension headaches typically affect both sides. Migraines often favor one side.
- Intensity: Tension headaches are mild to moderate. Migraines are moderate to severe.
- Physical activity: Tension headaches aren’t worsened by routine movement. Migraines are.
- Nausea and vomiting: Rare with tension headaches. Common with migraines.
- Light and sound sensitivity: Minimal with tension headaches. Pronounced with migraines.
- Aura: Does not occur with tension headaches. Occurs in some migraines.
- Duration: Tension headaches range from 30 minutes to days. Migraine attacks last 4 to 72 hours untreated.
Headache Patterns That Need Attention
Most headaches, including migraines, aren’t dangerous. But certain patterns signal something more serious. A sudden, explosive headache that reaches maximum intensity within seconds (often described as “the worst headache of my life”) needs emergency evaluation. The same goes for a headache accompanied by fever and a stiff neck, a headache after a head injury, or a new type of headache that appears for the first time after age 40.
Any significant change in your usual headache pattern also deserves a closer look. If your headaches are becoming more frequent, more intense, or behaving differently than before, that shift matters more than any single episode. Clinicians use the mnemonic SNNOOP10 to screen for warning signs, but the core idea is simple: new, sudden, or different headaches are the ones to take seriously.
Tracking Your Symptoms
If you’re unsure whether your headaches are migraines, keeping a simple log for a few weeks can be surprisingly revealing. Note when the headache starts and stops, where you feel the pain, whether it throbs or presses, and whether you experience nausea, light sensitivity, or any visual changes. Track whether moving around makes it worse. Record what you were doing before it started, what you ate, how you slept, and where you are in your menstrual cycle if applicable.
Patterns often emerge quickly. Many people discover their “bad headaches” have been migraines all along once they start paying attention to the accompanying symptoms. Migraine is the third leading cause of disability worldwide, yet it remains widely underdiagnosed, partly because people assume their symptoms are just a particularly bad headache. Recognizing the difference is the first step toward managing it effectively.
