A migraine is not just a bad headache. It’s a full-body neurological event that can last anywhere from 4 to 72 hours, with pain that throbs or pulses in intensity and gets worse when you do something as simple as walking up stairs. Most people who’ve never had one picture a really painful headache. The reality involves nausea, visual disturbances, extreme sensitivity to light and sound, and a recovery period that can feel like a hangover the next day.
The Pain Itself
Migraine pain is most often described as throbbing, pulsing, or pounding, though some people experience it as a deep, dull ache that slowly builds. It can hit one side of your head or both, and the location sometimes shifts during an attack. What makes migraine pain distinct from a tension headache or sinus pressure is how it responds to movement. Routine physical activity, even walking or bending over, makes it noticeably worse. Many people feel forced to lie completely still in a dark room because any motion intensifies the pain.
The intensity ranges from moderate to severe, and at its peak, it can make normal functioning impossible. You may not be able to read, look at a screen, carry on a conversation, or even think clearly. For children and teenagers, attacks can be shorter, sometimes lasting as little as two hours, but the experience is otherwise similar.
What Happens Before the Pain Starts
Many migraines don’t begin with head pain. They begin with a warning phase called the prodrome, which can start hours or even days before the headache hits. During this time, you might notice mood changes like irritability or a vague sense of depression, difficulty concentrating, fatigue, or a stiff neck and shoulders. Some symptoms are surprisingly specific: repeated yawning, unusual food cravings, and frequent urination are all hallmarks of this early phase. Not everyone recognizes these signs, but people who track their migraines often learn to spot them and use the window to prepare.
About 25 to 30 percent of people with migraines also experience aura, a set of sensory disturbances that typically develops over about five minutes and lasts up to an hour (though in roughly 20% of cases, it stretches longer). The most common form is visual. You might see shimmering or flickering lights, geometric patterns, or wavy lines that start near the center of your vision and spread outward. Some people describe it like looking through a kaleidoscope, or like heat ripples rising off a hot road. Others develop a blind spot, sometimes with a glittering border, called a scintillating scotoma. These blind spots can appear as rings, arcs, or C-shaped crescents of shimmering light.
Aura isn’t always visual. Some people feel numbness or tingling that starts in one hand, travels up the arm, and reaches the face, lips, and tongue. Others have trouble finding words or sound like they’re slurring their speech. These symptoms can be alarming, especially the first time they happen, because they can mimic a stroke.
Sensory Overload During an Attack
Beyond the pain, migraines hijack your senses. Light sensitivity (photophobia) and sound sensitivity (phonophobia) are so common that they’re part of the formal diagnostic criteria. Normal indoor lighting can feel blinding. A conversation at regular volume can feel like someone is shouting. Many people retreat to a quiet, dark room not because they want to, but because anything else is physically unbearable.
Smell sensitivity is less well known but surprisingly prevalent, affecting anywhere from 20% to over 80% of people during an attack, depending on the study. Perfume, cooking odors, or cleaning products that you’d normally ignore can trigger waves of nausea. In fact, more than half of people who experience smell sensitivity during a migraine also have it combined with nausea, light sensitivity, and sound sensitivity all at once. The sensory experience is cumulative: each stimulus stacks on top of the others.
Nausea is another defining feature. It can range from mild queasiness to active vomiting, and it often makes it difficult to eat, drink, or take oral medication during an attack.
Migraine Without Head Pain
Some people experience every other migraine symptom but skip the headache entirely. This is called a silent migraine, or acephalgic migraine. You might see the flickering lights and blind spots, feel the tingling or numbness spreading through your hand and face, have difficulty speaking, or feel intense dizziness and ringing in your ears. Without the headache to tie these symptoms together, silent migraines are often mistaken for other neurological conditions. If you experience visual disturbances or sudden speech difficulty without pain, it’s worth knowing that migraine is a possible explanation.
The “Migraine Hangover”
When the headache finally fades, the experience isn’t over. More than 80% of people who get migraines go through a postdrome phase, often called a migraine hangover. You’ll likely feel exhausted and sore throughout your body, with a stiff neck being especially common. Concentrating on a task or making decisions can feel unusually difficult, like your brain is running through fog. Some people also notice lingering light sensitivity, dizziness, or mood changes that swing from mild depression to an unexpected sense of euphoria.
The duration varies. For some, the hangover phase clears in a few hours. For others, it lingers into the next day. Combined with the prodrome, the attack itself, and the postdrome, a single migraine episode can disrupt three or four days of your life even when the actual headache lasts only a few hours.
How Migraine Pain Differs From Other Headaches
Tension headaches, the most common type, produce a steady, pressing tightness on both sides of your head, like a band squeezing around your skull. They don’t throb, they don’t get worse when you move, and they rarely cause nausea or sensitivity to light. Sinus headaches cause pressure and fullness around your cheekbones, forehead, or the bridge of your nose, often alongside congestion.
Migraine is different in several specific ways. The pain pulses rather than pressing. Physical activity makes it worse. It comes with at least one major associated symptom: nausea, vomiting, or sensitivity to both light and sound. And it lasts significantly longer, persisting for 4 to 72 hours if untreated. Doctors look for at least two of these four characteristics to distinguish migraine from other headache types: one-sided location, pulsating quality, moderate-to-severe intensity, and worsening with routine movement. If you’ve had five or more episodes matching this pattern, that’s the clinical threshold for a migraine diagnosis.
The combination of throbbing pain, sensory overload, nausea, and the inability to function normally is what separates a migraine from “just a headache.” People who’ve experienced both know the difference immediately.
