One of the most helpful things to understand is that a migraine attack often moves through phases rather than arriving all at once. According to the Mayo Clinic, an attack can pass through as many as four stages — prodrome, aura, headache, and postdrome — though not everyone experiences every phase, and many people never have aura at all. Learning to recognize these stages can help you notice an attack taking shape, sometimes well before the pain begins.
Prodrome: The Early Warning
The prodrome, sometimes called the premonitory phase, can begin hours or even a day or more before the headache itself. The signals are often subtle and easy to miss until you know to look for them. As described in MedlinePlus Magazine, a publication of the National Library of Medicine, prodrome symptoms can include mood changes, food cravings, frequent yawning, increased thirst or urination, and a growing sensitivity to light, sound, or smells.
Many people come to recognize their own personal version of this phase over time — a particular restlessness, a craving for something sweet, or a sense that the world has become a touch too bright. Noticing these cues can give you a valuable head start.
Aura: Reversible Neurological Symptoms
Aura is the phase that tends to draw the most questions, partly because it can feel dramatic and partly because only some people experience it. Research summarized in StatPearls indicates that roughly a quarter to a third of people with migraine have aura, which consists of fully reversible neurological symptoms. Most often these are visual — flashing lights, shimmering zigzag lines, or temporary blind spots — but aura can also involve tingling sensations or difficulty finding words.
Aura usually develops gradually over a few minutes and then fades, often giving way to the headache phase. Because some aura symptoms can overlap with signs of more serious conditions, it is worth discussing any new or unusual neurological symptoms with a healthcare provider so they can be properly evaluated.
The Headache Phase
This is the stage most people picture when they think of migraine. The pain is typically moderate to severe, often one-sided, and pulsating or throbbing, and it can last anywhere from 4 to 72 hours when an attack runs its course without treatment. Routine physical activity, even something as simple as climbing stairs, tends to make it worse.
The headache rarely travels alone. Nausea and sometimes vomiting are common companions, along with a heightened sensitivity to light, sound, and occasionally smells. That combination is exactly why so many people instinctively retreat to a dark, quiet room and wait for the storm to pass.
Postdrome: The Migraine Hangover
After the pain eases, many people enter a postdrome phase that can linger for a day or two. Often nicknamed the "migraine hangover," this stage can leave you feeling drained, foggy, and slow to concentrate, with some lingering sensitivity to light and sound. Being gentle with yourself during this recovery window — easing back into your routine rather than rushing it — can make the return to normal feel a little smoother.
