How Long Does a Migraine Last? What to Expect at Every Stage

One of the most disorienting things about migraines is that they don't have a predictable end time. Some people are back to normal in a few hours. Others are wiped out for two or three days. And the pain is just one part of it — the full migraine process often starts well before the headache and continues long after it resolves.

Here's a breakdown of what's actually happening at each stage, how long each phase typically lasts, and what that means practically.

The Four Stages of a Migraine

A full migraine attack can involve up to four distinct phases: prodrome, aura, headache, and postdrome. Not everyone experiences all four — many people skip the aura entirely — but understanding the full cycle helps you recognize where you are in it.

Stage 1: Prodrome (6 to 48 hours before the headache)

The prodrome is the pre-headache phase, sometimes called "premonitory symptoms." It can start anywhere from a few hours to two full days before the head pain arrives. During this phase, the migraine is already underway in terms of neurological changes — you just don't feel the headache yet.

Common prodrome symptoms include: neck stiffness or tension, unusual fatigue, mood changes (irritability, low mood, or sometimes unexpected euphoria), increased yawning, difficulty concentrating, food cravings, increased sensitivity to light or sound, and a general feeling of "something's off."

This phase matters because it's your warning window. Recognizing prodrome symptoms and acting on them — taking acute medication early, adjusting your schedule, eliminating other triggers — is one of the most reliable ways to reduce attack severity or sometimes abort an attack entirely.

Stage 2: Aura (20 to 60 minutes)

Aura occurs in roughly 25 to 30 percent of people with migraine. It involves reversible neurological symptoms that typically develop gradually over 5 to 20 minutes and then resolve within an hour. Visual auras are most common — zigzag lines, flickering lights, blind spots, or shimmering arcs in the visual field. Other auras involve sensory changes like tingling or numbness on one side of the face or hand, or speech and language disturbances.

Aura without headache also exists — this is called a silent migraine or acephalgic migraine (see our guide to silent migraine symptoms). The aura arrives and resolves without a pain phase following.

Stage 3: Headache (4 to 72 hours)

This is the phase most people associate with migraine. The International Headache Society defines migraine headache as lasting 4 to 72 hours, though most attacks that are treated promptly resolve in 4 to 24 hours. Untreated or undertreated attacks are more likely to extend toward that 72-hour upper limit.

The pain is typically moderate to severe, often one-sided (though not always), and described as throbbing or pulsating. It tends to worsen with physical activity. Nausea, vomiting, and severe sensitivity to light and sound are common during this phase and can be as debilitating as the pain itself.

If a migraine lasts more than 72 hours continuously, that's classified as status migrainosus — a medical situation worth discussing with your doctor, as it may require different treatment.

Stage 4: Postdrome (up to 48 hours)

After the headache resolves, many people spend anywhere from a few hours to two full days in the postdrome — often called the "migraine hangover." The pain is gone, but you may feel exhausted, mentally foggy, physically drained, and emotionally flat. Some people feel unusually calm or relieved. Cognitive function, in particular, often takes time to fully recover.

The postdrome is underappreciated as a source of real-world impact. You may feel "well enough" by conventional standards but be far below your normal baseline. Returning to full work or social commitments during postdrome often extends the overall recovery.

So How Long Does a Migraine Actually Last?

Adding it up: a full migraine cycle — from the first prodrome symptoms to the end of postdrome — can realistically span two to four days, even if the pain itself only lasted a day. This is why migraine is classified as a neurological disease rather than just "bad headaches." The impact on functioning extends well beyond the headache phase.

For most people with episodic migraine, individual attacks fall into one of these rough patterns:

• Short attacks (4 to 12 hours): Often treated early and effectively; more likely with prompt medication use
• Moderate attacks (12 to 24 hours): The most common range for an adequately managed attack
• Long attacks (24 to 72 hours): More common when medication is delayed, the attack is severe, or multiple triggers are stacked

What Actually Affects Duration

Several factors influence how long an individual attack lasts:

Time to treatment. The most consistent finding across migraine research is that treating earlier — at the very first sign of symptoms, ideally during prodrome or at headache onset — produces significantly shorter and milder attacks compared to waiting until pain is severe. Triptans in particular have a well-documented time-sensitivity: they're most effective in the first hour of headache onset.

Sleep. Sleep often ends or substantially shortens a migraine attack. This is one reason going to bed when possible is a reasonable management strategy.

Trigger stacking. When multiple triggers combine — a weather system moving through, a night of poor sleep, skipped meals, and caffeine withdrawal all at once — attacks tend to be longer and harder to treat. Single-trigger attacks often resolve more cleanly.

Medication overuse. Counterintuitively, overuse of acute medications (more than 10 to 15 days per month depending on the medication) can increase attack frequency and duration over time, a pattern called medication overuse headache.

Using Weather to Anticipate Attack Timing

If barometric pressure is one of your triggers, tracking forecasted pressure drops gives you a window into not just whether an attack is likely, but roughly when. A falling pressure system arriving over 48 hours often means the trigger window opens well before the front arrives — which aligns directly with where early intervention is most effective.

MigraineCast tracks barometric pressure trends at your location and surfaces those windows in advance, so you know when to be on alert for prodrome symptoms and when early action is most likely to shorten or abort the attack cycle.

Frequently Asked Questions

How long does a migraine typically last?

The headache phase of a migraine lasts 4 to 72 hours by clinical definition (International Headache Society criteria). Most treated attacks resolve in 4 to 24 hours. Untreated or undertreated attacks are more likely to extend toward 72 hours. The full migraine cycle — including prodrome (up to 48 hours before) and postdrome (up to 48 hours after) — can span 2 to 4 days even when the headache itself was shorter.

What are the 4 stages of a migraine?

The four phases are: (1) Prodrome — subtle neurological changes 6–48 hours before the headache, including fatigue, mood shifts, neck tension, and food cravings; (2) Aura — reversible neurological symptoms (visual, sensory, or speech) lasting 20–60 minutes, present in about 25–30% of people; (3) Headache — the pain phase, lasting 4–72 hours; (4) Postdrome — the "migraine hangover" of fatigue, brain fog, and low mood that can last up to 48 hours after pain resolves.

How long does the migraine hangover (postdrome) last?

The postdrome typically lasts a few hours to 48 hours after the headache resolves. Symptoms include exhaustion, difficulty concentrating, emotional flatness or unusual calm, and muscle soreness. Cognitive function often takes longer to return to full baseline than physical energy does. Returning to full activity during postdrome frequently extends overall recovery time.
