A migraine feels like intense, throbbing pain that pulses with your heartbeat, typically on one side of your head. But the pain is only part of the experience. A full migraine attack can last 4 to 72 hours and involves waves of nausea, extreme sensitivity to light and sound, and a kind of full-body shutdown that makes even walking across a room feel unbearable. Unlike a regular headache, a migraine is a neurological event that unfolds in stages, each with its own set of sensations.
The Pain Itself
Migraine pain is pulsating. It throbs in rhythm, intensifying with each heartbeat. Most people feel it on one side of the head, though it can occur on both sides or switch sides between episodes. The intensity ranges from moderate to severe, and it gets noticeably worse with physical activity. Something as simple as bending over to pick something up, climbing stairs, or turning your head quickly can send a sharp spike through your skull.
This is one of the clearest differences between a migraine and a tension headache. Tension headaches produce a dull, steady pressure that wraps around the head like a tight band. They’re usually mild to moderate and don’t worsen when you move. A migraine, by contrast, forces you to stop moving. Most people retreat to a dark, quiet room because staying upright and active feels physically impossible.
Warning Signs Before the Pain Starts
Many migraine attacks begin hours or even a day before the headache itself, with a phase called the prodrome. These early warning signs are easy to dismiss as just feeling “off,” but they follow a recognizable pattern. In a large clinical trial published in Neurology Clinical Practice, the most common prodrome symptoms were sensitivity to light (57% of episodes), fatigue (50%), neck pain (42%), sensitivity to sound (34%), and dizziness (28%).
Irritability showed up in about 26% of episodes, nausea in 23%, and difficulty concentrating in 21%. Some people notice excessive yawning, muscle soreness, blurred vision, or sensitivity to smell. The experience can feel like the early stages of getting sick: you’re tired for no reason, your neck is stiff, you can’t focus, and everything around you feels slightly too loud or too bright. People who learn to recognize these signals sometimes have a narrow window to treat the attack before full pain sets in.
What a Visual Aura Looks Like
About one in four people with migraines experience an aura, usually in the 20 to 60 minutes before the headache arrives. Visual aura is the most common type, and it’s unlike anything you’d experience with a regular headache.
The hallmark is a scintillating scotoma: a shimmering, glittering blind spot in your field of vision. People describe it like looking through a kaleidoscope, or like the heat ripples that distort the air above hot pavement. The patterns can take several forms. Some appear as jagged, zigzagging lines (called fortification patterns because they resemble the walls of a medieval fort). Others look like arcs or crescents of flickering light that curve around the center of your vision, sometimes forming a complete ring. Checkerboard patterns of black-and-white squares are another variation. These visual disturbances shimmer, pulse, and expand over the course of several minutes before fading.
During an aura, you may also lose patches of your vision entirely, notice tingling or numbness creeping up one arm, or have difficulty finding words. The whole experience can be disorienting and, for first-timers, genuinely frightening.
Sensory Overload During an Attack
One of the most defining features of a migraine is how your senses become amplified to a painful degree. Normal indoor lighting feels blinding. A conversation at regular volume sounds like shouting. Cooking smells or perfume can trigger a wave of nausea.
About 69% of people with migraines meet clinical thresholds for light sensitivity, and for many, this sensitivity doesn’t fully go away between attacks. Roughly one in four also experiences a phenomenon where their skin becomes hypersensitive to touch. Wearing a ponytail, resting your head on a pillow, or even feeling your glasses on your face can become genuinely painful. This sensory amplification is part of why migraines are so much more disabling than headaches. It’s not just that your head hurts. Your entire sensory system is turned up to a level that makes the normal world intolerable.
Nausea and Stomach Symptoms
The nausea that comes with a migraine isn’t the mild queasiness of a skipped meal. It can be deep, persistent, and severe enough to cause vomiting. During an attack, your stomach actually slows down. Gastric emptying, the process of moving food and liquid out of your stomach, becomes delayed. This is why eating feels impossible during a migraine, and why oral medications often don’t work well. The pills sit in a sluggish stomach instead of being absorbed.
This digestive slowdown also explains why some people feel bloated or lose their appetite in the hours leading up to a migraine, even before the pain begins. The gut and the brain are in close communication, and during a migraine attack, both systems are affected.
Dizziness and Vertigo
Some migraines involve vertigo: a spinning sensation where the room tilts or moves around you, even when you’re sitting still. This is characteristic of vestibular migraines, which can cause episodes of dizziness lasting anywhere from five minutes to 72 hours. The vertigo can be severe enough to make standing unsafe, and it often comes with nausea and vomiting that have nothing to do with the headache pain itself.
Even without full vertigo, many people with migraines feel lightheaded or unsteady during an attack. Walking in a straight line takes conscious effort. The combination of dizziness, pain, and sensory overload is what makes many people describe a migraine as a completely incapacitating experience.
The Migraine Hangover
When the headache finally breaks, the migraine isn’t over. The postdrome phase, often called the migraine hangover, can linger for up to 48 hours. It feels remarkably similar to an alcohol hangover: deep fatigue, body aches, a stiff neck, and a foggy inability to concentrate or make decisions.
You might feel like you’re thinking through mud. Light and sound sensitivity often persist at a lower level. Some people experience dizziness or lingering nausea. Mood shifts are common during this phase and can swing in either direction, from a strange sense of euphoria to feeling flat and depressed. The overall sensation is one of being drained, as if your body just fought off an illness. Many people describe the day after a migraine as a “lost day” where they can function but not at anything close to full capacity.
How It Differs From a Regular Headache
The distinction comes down to the full-body nature of the experience. A tension headache is localized discomfort. A migraine hijacks your nervous system. The throbbing quality, the worsening with movement, the nausea, the sensory hypersensitivity, and the multi-phase timeline that stretches from prodrome to postdrome all set it apart. A tension headache lasts 30 minutes to several hours and you can usually push through it. A migraine can sideline you for three days straight, from the first neck stiffness to the last traces of brain fog.
People who live with chronic migraines often note that the hardest part to explain isn’t the pain. It’s the invisible symptoms: the constant low-grade sensitivity to sound between attacks, the cognitive fog, the way a fluorescent-lit office feels like an endurance test. As one patient put it, it’s much easier to say “I have a headache” than to explain that sound bothers you all the time, and that chronic sensory sensitivity is what truly disrupts your work, relationships, and daily life.
