A migraine feels like a pulsating, throbbing pain that often concentrates on one side of your head, though about 40% of people experience it on both sides. But the pain is only part of it. Migraines affect your entire nervous system, producing waves of nausea, extreme sensitivity to light and sound, and a mental fog that can linger for days. Roughly 14% of the global population experiences migraines each year, and each attack unfolds in distinct phases with its own set of sensations.
The Throbbing Pain and Why It Pulses
The hallmark sensation of a migraine is a pulsating quality that often syncs with your heartbeat. This is different from a tension headache, which feels like a steady band of pressure squeezing both sides of your head. Migraine pain is moderate to severe, and it gets worse with routine physical activity. Walking up stairs, bending over to pick something up, or even just moving your head can amplify the throbbing.
That pulsing sensation comes from pain-signaling nerves in and around your head becoming hypersensitive. During an attack, nerve cells release inflammatory proteins that sensitize surrounding tissue, creating a feedback loop where normal sensations register as painful. This is why, at the peak of a migraine, even light touch on your scalp or face can hurt. Brushing your hair, wearing glasses, or resting your head on a pillow can feel genuinely painful. This phenomenon, called allodynia, is one of the most disorienting parts of a severe attack.
What Happens Before the Pain Starts
Many people feel a migraine building hours before the headache itself arrives. About 38% of migraine patients experience a prodrome phase that starts at least two hours before the pain. These early warning signs include mood shifts (irritability or unexplained sadness), difficulty concentrating, a stiff neck and shoulders, fatigue, and food cravings. Some people yawn repeatedly or urinate more frequently. These symptoms can feel confusing because they don’t seem connected to a headache.
Sensitivity to light, sound, and smell often begins during this early phase too, not just during the headache. Research suggests your brain’s threshold for processing sensory input drops before an attack, so stimuli that normally wouldn’t bother you (sunlight through a window, a coworker’s perfume) start to feel intrusive and unpleasant. Many people mistake these sensory irritants as triggers for their migraine, when they’re actually the first symptoms of one already in progress.
Visual Aura and Sensory Disturbances
About a third of people with migraines experience an aura, typically in the 20 to 60 minutes before the headache phase. Visual aura is the most common type and is unlike anything you experience in normal life. It usually starts near the center of your vision as a small shimmering spot or blind spot, then gradually expands outward toward the edges of your visual field. People describe seeing zigzag lines, flashing lights, kaleidoscope patterns, or sparkling dots that migrate across their vision.
In roughly a third of aura cases, sensory symptoms accompany the visual ones. A tingling or numbness might start in one hand, slowly travel up that arm, and reach your face, lips, and tongue. Some people temporarily struggle to find words or sound like they’re slurring. Each individual type of aura symptom typically lasts less than an hour, though experiencing multiple types in sequence can stretch the total duration longer. The slow, creeping spread of these symptoms (as opposed to the sudden onset you’d see with a stroke) is a distinguishing feature of migraine aura.
During the Attack: More Than Just Head Pain
The headache phase is when most people feel at their worst, and the pain is only one piece of it. Nausea is extremely common and can escalate to vomiting. Light feels piercing, even at low levels, so many people retreat to dark rooms. Sound sensitivity means normal conversation volume feels too loud. Some people become sensitive to smells, where cooking odors or perfume become nauseating. Anxiety and an inability to sleep often layer on top of everything else.
The intensity can make it impossible to work, drive, or carry on a conversation. Many people describe a feeling of their head being squeezed from the inside while simultaneously being hammered from the outside. Moving makes it worse. Thinking makes it worse. The pain is often so consuming that you can’t focus on anything else, and many people simply lie still in a dark, quiet room waiting for it to pass. An untreated attack can last anywhere from 4 to 72 hours.
The Migraine Hangover
When the headache finally fades, most people don’t feel normal right away. The postdrome phase, often called a migraine hangover, can last anywhere from a few hours to two full days. You feel drained, like you’ve been physically ill. Your body aches, especially your neck. Concentrating on even simple tasks feels like pushing through thick fog, and making decisions becomes surprisingly difficult.
Dizziness is common during this phase, sometimes enough to make the room feel like it’s spinning and to bring back nausea. Light and sound sensitivity often persist at lower levels. Your mood can swing unpredictably, from feeling oddly euphoric (a relief response) to sliding into sadness or irritability. Resting in a dark, quiet space continues to help. Many people find this phase frustrating because the pain is gone but they still can’t function normally.
How Migraines Differ From Tension Headaches
People often wonder whether what they’re experiencing is a migraine or a regular headache. The differences are consistent enough to tell them apart. Tension headaches produce a pressing, tightening sensation on both sides of your head, are mild to moderate in intensity, and don’t get worse when you move around. Migraines pulse, tend to favor one side (about 60% of the time), hit moderate to severe intensity, and worsen with physical activity.
The clearest distinguishing features are the accompanying symptoms. Tension headaches don’t cause nausea, vomiting, or significant sensitivity to light and sound. Migraines do. If your headache makes you want to lie down in a dark room, if bending over intensifies it, if light or noise feels unbearable, those point strongly toward migraine.
Migraines Without Head Pain
Not all migraines involve a headache, which can be confusing. Silent migraines produce all the aura and neurological symptoms (visual disturbances, tingling, difficulty speaking, dizziness, ringing in the ears) without progressing to head pain. You might see bright expanding lights or zigzag lines, experience numbness that creeps from your hand up your arm to your face, or suddenly struggle to get words out. These episodes are disorienting and can mimic symptoms of a stroke, though they develop gradually rather than all at once.
Vestibular migraines are another variation where the dominant sensation is vertigo and imbalance rather than pain. People describe it in ways that go beyond simple dizziness: feeling like they’ve stepped into a hole, like they’re inside a spinning barrel, or like the ground has shifted beneath them. These sensations can be so difficult to articulate that patients often feel they aren’t believed. Vestibular migraines can occur with or without a headache, making them especially tricky to identify.
