Migraine symptoms go well beyond a bad headache. A migraine attack unfolds in distinct phases, each with its own set of symptoms that can start days before the pain hits and linger after it fades. The experience typically includes intense, throbbing head pain alongside nausea, sensitivity to light and sound, and sometimes visual disturbances. Understanding the full picture helps you recognize what’s happening at each stage.
The Four Phases of a Migraine Attack
A migraine attack can include up to four phases: prodrome, aura, headache, and postdrome. Not everyone experiences all four, and the phases can vary from one attack to the next. But recognizing the earlier phases gives you a head start on managing what comes next.
Prodrome: Early Warning Signs
The prodrome phase is your body’s advance notice. It can begin 2 to 48 hours before the headache starts, and its symptoms are easy to dismiss as a bad day or poor sleep. They fall into a few broad categories:
- Mood and cognitive changes: anxiety, irritability, depression, difficulty focusing, and fatigue
- Sensory sensitivity: early sensitivity to light, sound, or smells
- Autonomic symptoms: bloating, nausea, constipation, frequent urination, and increased thirst
- General symptoms: excessive yawning, neck stiffness, and eye discomfort
Fatigue, neck stiffness, and mood changes are among the most commonly reported prodrome symptoms. Many people who get migraines learn to recognize their personal pattern of warning signs over time. Some notice food cravings during this phase, which historically led to the misconception that certain foods “trigger” migraines when they were actually a symptom of the attack already underway.
Aura: Visual and Sensory Disturbances
About one in four people with migraines experience aura, a phase of neurological symptoms that typically develops over 5 to 60 minutes and resolves before or during the headache. Visual disturbances are the most common type and can include:
- Blind spots (scotomas), sometimes outlined by geometric shapes
- Zigzag lines that float slowly across your field of vision
- Shimmering spots or stars
- Flashes of light
- Partial vision loss
Aura isn’t limited to vision. Some people feel tingling that starts in one hand or on one side of the face, then slowly spreads along the arm or leg before turning into numbness. Tingling or numbness of the tongue and mouth can also occur. In rarer cases, aura causes speech difficulty, muscle weakness, or temporary hearing changes like ringing in the ears. These symptoms can be alarming, especially the first time they happen, but they are temporary and resolve on their own.
The Headache Phase
The headache itself is what most people think of when they hear “migraine,” and it’s distinct from a tension headache or sinus pressure in several ways. The pain is typically throbbing or pulsating, often concentrated on one side of the head, though it can affect both sides. Throbbing pain is the single quality most strongly associated with migraine, and it correlates with the highest levels of severity and disability.
A migraine headache generally lasts between 4 and 72 hours without treatment. During this phase, pain intensifies with routine physical activity. Even walking up stairs, bending over, or turning your head can make it worse. The pain is moderate to severe for most people, sometimes reaching a level that makes normal functioning impossible.
Nausea, Light, and Sound Sensitivity
The headache phase comes with a cluster of associated symptoms that can be just as debilitating as the pain itself. In one population-based study, sensitivity to sound affected about 81% of people with migraine, sensitivity to light affected roughly 74%, and nausea hit about 71%. Nearly half experienced vomiting.
When people were asked which single symptom bothered them the most, nausea was the overwhelming winner, reported as the most bothersome symptom by about 62% of migraine sufferers. Sound sensitivity came in second at 25%. These accompanying symptoms are a major reason migraines force people to retreat to dark, quiet rooms. Even moderate light or everyday conversation-level noise can feel unbearable.
What Causes These Symptoms
Migraine is a neurological condition, not simply a blood vessel problem as was once believed. During an attack, a key nerve system that runs through the face and head becomes activated and releases a signaling molecule that sets off a chain reaction. This molecule triggers the production of nitric oxide and sensitizes nearby nerve fibers, essentially turning up the volume on pain signals. That sensitization spreads from the peripheral nerves to the central nervous system, which is why the pain can feel so intense and widespread, and why even light touch on the scalp or face can become painful during an attack.
This process also explains why symptoms build gradually rather than hitting all at once. The sensitization cascades outward, recruiting more nerve fibers and amplifying sensory input of all kinds. That’s why light, sound, smell, and movement all become intolerable during the headache phase.
Vestibular Migraine: When Dizziness Is the Main Symptom
Not all migraines follow the classic pattern. Vestibular migraine causes episodes of vertigo, unsteadiness, and sensitivity to motion that can last minutes, hours, or even days. What makes this type tricky to recognize is that the vestibular symptoms can occur with or without an actual headache. Some people experience dizziness and balance problems as their primary symptom, with head pain playing a minor role or not showing up at all.
People with vestibular migraine may also notice visual aura or heightened sensitivity to visual stimulation, like scrolling on a screen or watching things move past a car window. These attacks can happen at different times from traditional headache attacks, making the connection to migraine easy to miss.
Postdrome: The Migraine Hangover
Once the headache fades, the attack isn’t necessarily over. The postdrome phase, often called the “migraine hangover,” can last hours to a full day or more. In an electronic diary study that tracked symptoms in real time, tiredness was the most common postdrome symptom, reported in 88% of episodes. Difficulty concentrating appeared in 56%, and neck stiffness in 42%.
Reduced mood is also common during this phase, along with lingering sensitivity to light and sound at lower levels than during the headache itself. Some people experience mild nausea or gastrointestinal discomfort that carries over. The postdrome can feel like recovering from the flu: you know the worst is over, but your body and brain aren’t quite back to normal. Most people find that rest, hydration, and avoiding intense mental or physical effort help them get through this phase more comfortably.
Migraine Without Head Pain
It’s worth knowing that some migraine attacks produce aura symptoms, nausea, or light sensitivity without significant head pain. This is sometimes called “silent migraine” or “acephalgic migraine.” People who experience this may have visual disturbances, brain fog, or nausea and not realize they’re having a migraine because the headache never materializes. This is more common in people who had migraines with pain earlier in life and find the headache component fading with age, though it can happen at any stage.
Recognizing Your Pattern
Migraine symptoms vary significantly from person to person and even between attacks in the same person. Some people always get aura; others never do. Some find nausea their worst symptom while others are most disabled by light sensitivity. Tracking your own pattern across the full timeline, from prodrome through postdrome, gives you the best chance of catching attacks early and understanding what your body is telling you. A simple log of symptoms, timing, and severity over several attacks can reveal your personal migraine signature more clearly than any general description.
