A migraine is far more than a bad headache. It’s a neurological event that unfolds in stages, often starting hours before the pain hits and lingering long after it fades. The hallmark sensation is moderate to severe throbbing pain, usually on one side of the head, paired with nausea and an almost unbearable sensitivity to light and sound. An untreated attack lasts anywhere from 4 to 72 hours.
The Warning Signs Before Pain Starts
Most migraines announce themselves hours in advance through a collection of subtle symptoms called the prodrome. In a large screening study of nearly 5,000 migraine episodes, the most common early warning signs were sensitivity to light (57%), fatigue (50%), neck pain (42%), sensitivity to sound (34%), and difficulty thinking or concentrating (30%). Other frequent signals included irritability, nausea, muscle aching, blurred vision, and excessive yawning.
These symptoms don’t feel dramatic. You might just notice you’re unusually tired, that your neck feels stiff, or that the overhead lights at work seem harsher than normal. Many people describe a vague sense that something is “off” without being able to pinpoint it. About 80% of the time, these early symptoms are followed by head pain within one to six hours.
Aura: Visual and Sensory Distortions
Roughly one in four people with migraines experience an aura, a wave of neurological symptoms that typically lasts 10 to 30 minutes before the headache begins. The most recognized form is visual. It often starts as a small hole of light or a cluster of bright geometric shapes in your field of vision. This can expand into a crescent or C-shaped object with shimmering zigzag lines along its leading edge, sometimes called a fortification spectrum because the pattern resembles the walls of a medieval fort. Some people see flashing lights, bright spots, or experience partial vision loss where a blank patch blocks part of what they’re looking at.
Sensory auras feel different. They typically begin as tingling in one hand or arm that slowly creeps upward over 10 to 20 minutes, sometimes spreading to one side of the face and tongue. The sensation is similar to the pins-and-needles feeling of a limb “falling asleep,” except it moves deliberately across the body.
What the Pain Actually Feels Like
The headache phase is what most people picture when they think of a migraine, and it’s distinct from an ordinary headache in several specific ways. The pain pulses or throbs rather than pressing steadily. It concentrates on one side of the head rather than wrapping around both temples. It’s intense enough to stop you from doing normal activities. And it gets noticeably worse with routine physical movement like walking up stairs, bending over, or even just shifting position.
A tension headache, by contrast, feels like a band of pressure squeezing both sides of the head. The pain is usually mild to moderate, steady rather than pulsing, and doesn’t worsen when you move around. People with tension headaches can generally push through their day. Migraines make that extremely difficult or impossible.
The pain itself can range from a deep, rhythmic pounding to a sharp, drilling sensation behind one eye. Some people feel it in the temple, others along the jaw or the back of the skull. The location can shift between attacks or even during a single episode.
Sensitivity to Everything
Pain is only part of the experience. Over 80% of people with migraines develop photophobia and phonophobia during an attack, meaning light and sound become physically painful. A normally comfortable room can feel like staring into a spotlight while someone bangs a drum next to your ear. Many people retreat to a dark, quiet room not out of preference but out of necessity.
Smell sensitivity is common too. Perfume, cooking odors, or cleaning products that you’d normally ignore can become overwhelming and trigger waves of nausea. The nausea itself ranges from mild queasiness to active vomiting, which can make it hard to keep down food, water, or medication. This combination of sensory overload and stomach distress is one of the reasons migraines are so disabling. Even basic tasks like reading a phone screen, listening to a conversation, or sitting under fluorescent lights become unbearable.
How It Feels After the Pain Ends
When the headache finally subsides, the migraine isn’t necessarily over. The postdrome, sometimes called a “migraine hangover,” can last up to 48 hours. You’ll likely feel exhausted and sore throughout your body, especially in your neck and shoulders. Concentrating on a specific task or making decisions feels unusually hard, as if your brain is working through fog.
Some people also notice mood swings during this phase, ranging from unexpected euphoria to a low, depressed feeling. Light and sound sensitivity can linger. Dizziness is common. The overall sensation is similar to the day after a bad flu: you’re functional, but everything takes more effort than it should.
How Migraine Differs by Type
Not every migraine follows the classic pattern of one-sided throbbing pain. Vestibular migraines center on dizziness and balance problems rather than head pain. The primary sensation is vertigo, a feeling that you or the room around you is spinning or tilting. This can last minutes, hours, or in some cases days, and comes with unsteadiness and a heightened sensitivity to motion. Some people with vestibular migraines have minimal head pain, which makes them harder to recognize as migraines at all.
Hemiplegic migraines add temporary muscle weakness on one side of the body, mimicking a stroke. During the aura phase, one arm or leg may feel heavy and difficult to move. A simple test is raising both arms overhead: one will feel significantly harder to lift and hold up. Numbness and tingling spread through the face, arm, and leg on the affected side. The weakness typically resolves as the headache phase progresses, but it can be frightening, especially the first time it happens.
Why Migraines Feel So Different From Headaches
The intensity and complexity of a migraine comes down to what’s happening in the nervous system. Ordinary headaches involve muscle tension or blood vessel changes in the head and neck. Migraines involve a dysfunction in the network of nerves that relay pain signals from the head to the brain. When this system misfires, it triggers a cascade of inflammation around the brain’s blood vessels, amplifies pain signals, and throws sensory processing into overdrive. That’s why light hurts, sound hurts, smells are overwhelming, and the pain throbs in sync with your heartbeat.
This neurological disruption also explains why migraines produce so many symptoms beyond pain. The brain fog, mood changes, food cravings, yawning, and fatigue in the hours before and after the headache aren’t side effects. They’re part of the same underlying event, driven by shifts in brain activity that begin well before pain starts and continue after it stops.
