A migraine unfolds in four distinct stages: prodrome, aura, headache (the attack), and postdrome. Not everyone experiences all four. About 75% of people with migraines skip the aura phase entirely, and the prodrome and postdrome can be subtle enough to go unnoticed. But understanding each stage helps you recognize a migraine earlier, treat it more effectively, and know what to expect as it runs its course.
Stage 1: Prodrome
The prodrome is your earliest warning sign, sometimes appearing hours or even a full day before the headache hits. Think of it as the migraine’s opening act. The most common prodrome symptoms are fatigue and tiredness (reported by about 80% of people), nausea (85%), sensitivity to light (65%), neck pain or stiffness (60%), and dizziness (50%). Other signals include food cravings, mood changes, difficulty concentrating, and excessive yawning.
These symptoms don’t all arrive at the same time. Fatigue and neck stiffness tend to show up earliest, roughly 4 to 5 hours before headache onset. Nausea and light sensitivity creep in much closer to the headache, often within an hour or two. For most people, the window between the first prodrome symptom and the start of head pain falls between 1 and 6 hours. Learning your personal pattern can give you a real head start on treatment.
Stage 2: Aura
Only about 25% of people with migraines experience aura, making this the one stage most people skip. When it does occur, aura involves temporary neurological symptoms that typically last less than 60 minutes. It usually appears just before the headache, though it can overlap with the pain phase.
Visual disturbances are the hallmark of aura. These can include zigzag lines drifting across your field of vision, shimmering spots, flashes of light, blind spots (sometimes outlined by geometric shapes), or partial vision loss. These visual changes affect both eyes, which distinguishes them from eye-specific problems.
Aura isn’t always visual, though. Some people feel tingling that starts in one hand and slowly spreads up the arm, or tingling on one side of the face that gradually moves to include the lips or tongue. Less commonly, aura can cause temporary difficulty speaking, muscle weakness on one side of the body, or ringing in the ears. The slow, spreading quality of these symptoms is a key feature. They build gradually over minutes rather than appearing all at once.
What’s happening in the brain during aura is a phenomenon called cortical spreading depression. A wave of intense electrical activity sweeps slowly across the brain’s surface, temporarily silencing normal brain function in its path for several minutes. This wave moves at roughly the same pace that aura symptoms spread across your visual field or along your arm, which is why the experience feels like it’s creeping rather than striking suddenly.
About 5% of people with migraines experience what’s called a silent migraine, where aura occurs without any headache following it. This is more common in people over 50 who had migraines with aura earlier in life.
Stage 3: The Headache Attack
The attack phase is what most people think of when they hear “migraine.” The pain is typically throbbing or pulsing, usually concentrated on one side of the head, and lasts anywhere from 4 to 72 hours without treatment. In children and adolescents, attacks can be shorter, potentially lasting as little as 2 hours.
The headache itself is only part of the picture. During an attack, you’re likely dealing with nausea, sensitivity to light and sound, and worsening pain with physical movement. Even routine activities like walking up stairs or bending over can intensify the throbbing. Many people find they need to lie still in a dark, quiet room until the worst passes.
Timing your treatment matters. Taking medication during the earliest, mildest pain of the attack phase is significantly more effective than waiting until the pain is severe. Research has shown that ineffective acute treatment doubles the risk of migraines becoming chronic, meaning 15 or more headache days per month. This creates a cycle where poorly managed attacks lower the threshold for future ones through changes in how the brain processes pain signals.
Common triggers for the attack phase include stress, hormonal changes (particularly around menstruation), loud noises, and strong odors. Identifying your personal triggers won’t prevent every attack, but it can reduce their frequency.
Stage 4: Postdrome
After the headache resolves, most people enter the postdrome, often called the “migraine hangover.” This final stage can last anywhere from a few hours to two full days. The pain is gone, but you don’t feel normal yet.
Postdrome symptoms include fatigue, body aches (especially a stiff neck), difficulty concentrating, lingering nausea, and continued sensitivity to light and sound. Some people describe a mental fog that makes it hard to think clearly or find words. Mood changes during postdrome can swing in either direction. Some people feel mildly euphoric, while others feel depressed or irritable.
The postdrome is often overlooked, but it’s a real part of the migraine that affects your ability to function. If you’ve ever felt “off” for a day or two after a migraine, you weren’t imagining it.
Not Every Migraine Follows All Four Stages
The four-stage framework is useful for understanding the full scope of what a migraine can involve, but individual attacks vary widely. You might have a clear prodrome before one migraine and no warning at all before the next. Some people never experience aura. Others have a barely noticeable postdrome. The headache phase is the most consistent, but even its severity and duration fluctuate from attack to attack.
For a formal migraine diagnosis, clinicians look for at least five attacks with headaches lasting 4 to 72 hours that include specific features like one-sided pain, pulsing quality, moderate to severe intensity, or worsening with routine physical activity. If you’ve had fewer than five attacks that fit this pattern, the diagnosis is classified as “probable migraine” rather than confirmed.
Tracking your own stages over multiple attacks can reveal patterns you’d otherwise miss. Recognizing that neck stiffness or unusual fatigue is your personal prodrome signal, for instance, gives you a window to treat early, when medication is most likely to work.
