A migraine feels like a throbbing, pulsing pain that often hits one side of your head, while a regular tension headache produces a steady, dull pressure across your entire head or around your forehead and the back of your skull. But the pain itself is only part of the story. Migraines come with a package of symptoms that can affect your vision, stomach, and ability to function, making them a fundamentally different experience from a typical headache.
How the Pain Differs
Tension headaches, the most common type, cause mild to moderate steady pain. People often describe it as a band of pressure squeezing around the head, especially across the forehead or at the base of the skull. The pain stays relatively even and doesn’t pulse or throb.
Migraine pain is moderate to severe and has a distinct throbbing quality that often syncs with your heartbeat. It tends to concentrate in one area: a temple, behind one eye, or the back of the head on one side. Physical activity makes it worse. Bending over to pick something up, climbing stairs, or even just walking can intensify the pounding. With a tension headache, movement doesn’t typically change the pain.
There’s an interesting overlap, though. As a tension headache gets more intense, it starts to feel more like the sharp, throbbing pain of a migraine. And when migraines become very frequent, their character can blur toward the steady ache of a tension headache. This is one reason people sometimes struggle to tell the two apart.
Symptoms Beyond the Pain
The clearest way to distinguish a migraine from a headache is everything that comes along with it. Tension headaches are essentially just pain. Migraines bring a constellation of other symptoms that affect your whole body.
Nausea is one of the most common, sometimes progressing to vomiting. Sensitivity to light and sound can become so intense that you need to retreat to a dark, quiet room. Many people also develop sensitivity to smells, where perfume or cooking odors become unbearable. You may feel anxious, have trouble sleeping during the attack, or find it impossible to concentrate on anything.
About one in four people with migraines experience aura, a set of neurological symptoms that usually appear before the head pain begins and last up to 60 minutes. Visual aura is the most common type. You might see zigzag lines floating across your vision, shimmering spots, flashes of light, or blind spots that start in the center of your visual field and spread outward. Some people get tingling in one hand or one side of the face that slowly travels along the arm, sometimes turning into numbness. Less commonly, aura can affect speech, making it hard to find words or speak clearly.
The Four Phases of a Migraine Attack
Unlike a headache that simply starts and stops, a migraine often unfolds in distinct stages that can stretch over days.
The first phase, called prodrome, can begin hours or even days before the actual pain. Symptoms are subtle and easy to miss: unexplained mood changes, irritability, difficulty focusing, fatigue, neck stiffness, food cravings, frequent urination, or excessive yawning. Some people learn to recognize these as early warning signs that an attack is coming.
Aura, when it occurs, is the second phase. It typically develops gradually over at least five minutes, though in about 20% of people it can last longer than an hour. Sometimes aura doesn’t precede the headache at all but shows up after the pain has already started.
The headache phase is the most recognizable part of the attack. It typically lasts several hours to up to three days. Compare that with tension headaches, which can be as brief as 30 minutes, though they can also stretch over a few days in some cases.
The final phase, sometimes called a “migraine hangover,” lingers after the pain fades. You might feel wiped out, achy, dizzy, or unable to concentrate. Many people describe this phase as feeling like they’ve run a marathon. It varies in length but can last a full day or more, which means a single migraine attack from start to finish can occupy the better part of a week.
Why Migraines Feel So Different
The reason a migraine is so much more intense than a tension headache comes down to what’s happening in your nervous system. During a migraine, a network of nerves that connects blood vessels in your skull to your brainstem becomes activated. When this system fires, it releases signaling molecules that trigger inflammation around the brain’s protective covering. Blood vessels dilate, pain receptors become sensitized, and the result is that deep, pulsing pain that worsens with every heartbeat.
This nerve activation also explains the nausea, light sensitivity, and other symptoms. The signals spread through interconnected brain pathways that affect vision, digestion, and sensory processing, which is why a migraine feels like a whole-body event rather than just head pain. In people who get aura, a slow wave of electrical activity spreads across the brain’s surface before the pain begins, temporarily disrupting normal brain function in whatever region it passes through.
Tension headaches involve different mechanisms. They’re thought to stem from muscle tightness, stress responses, and changes in pain processing, but they don’t trigger the same inflammatory cascade. That’s why the pain stays duller and doesn’t come with the full package of neurological symptoms.
How Migraines Affect Daily Life
A tension headache is usually something you can push through. You might reach for an over-the-counter pain reliever and carry on with your day. Migraines are a different story. The World Health Organization ranks migraine as the third highest cause of disability worldwide among neurological conditions, behind only stroke and a type of brain injury in newborns.
During an attack, many people can’t work, drive, or care for their families. The combination of severe pain, nausea, and sensory sensitivity makes normal activity impossible. Even between attacks, the unpredictability of migraines affects career decisions, social plans, and mental health. People often try to push through the symptoms, but the resulting drop in productivity and the strain on relationships takes a real toll over time.
Red Flags That Need Immediate Attention
Most headaches and migraines, while painful, aren’t dangerous. But certain headache patterns signal something more serious.
- Sudden, explosive onset: A headache that hits maximum intensity within seconds, sometimes called a thunderclap headache, can indicate a blood vessel problem like an aneurysm and needs emergency evaluation.
- New neurological symptoms: Weakness in an arm or leg, numbness that isn’t part of your usual migraine pattern, or vision changes that don’t resolve deserve prompt medical attention.
- Fever, night sweats, or weight loss: These systemic symptoms alongside a headache can point to an infection or other underlying condition.
- New headaches after age 50: A headache pattern that starts for the first time later in life is more likely to have a secondary cause.
- Steady worsening: A headache that keeps getting more severe or more frequent over weeks, rather than coming and going, warrants investigation.
- Position-dependent pain: Pain that changes significantly when you stand up, lie down, or strain (coughing, bearing down) can indicate a pressure-related issue.
A new, very severe headache with sudden onset is the most concerning of these and is the clearest reason to seek emergency evaluation, including imaging.
