A typical migraine headache lasts between 4 and 72 hours when untreated. That’s the diagnostic window used by the International Headache Society, and it holds true for most adults. But the full migraine experience, from the earliest warning signs to the lingering “hangover” afterward, can stretch well beyond that three-day window.
The Headache Phase: 4 to 72 Hours
The headache itself is what most people think of as “the migraine,” and it typically falls within that 4-to-72-hour range. Some people get attacks that resolve in half a day; others endure pain that builds and persists for a full three days. Where you fall on that spectrum can vary from one attack to the next, depending on how quickly you treat it, how well you slept, your stress level, and other triggers.
Children and teenagers tend to have shorter attacks. For kids under 15, migraines can be as brief as 2 hours and rarely exceed 48 hours. If your child’s headaches seem to end faster than your own, that’s normal and doesn’t mean they’re experiencing something different.
The Full Timeline: Start to Finish
A migraine is more than just a headache. It moves through up to four distinct phases, and understanding them helps explain why you might feel “off” for days surrounding a single attack.
Prodrome begins hours to days before the headache arrives. You might notice food cravings, unusual yawning, irritability, neck stiffness, or difficulty concentrating. Not everyone recognizes these signs, but people who track their migraines often learn to spot them as early warnings.
Aura affects roughly one in four people with migraines. It produces visual disturbances (like zigzag lines or blind spots), tingling in the face or hands, or difficulty speaking. Aura symptoms spread gradually over 5 to 60 minutes and typically resolve before or shortly after the headache begins.
Headache is the main event: throbbing or pulsing pain, usually on one side of the head, often accompanied by nausea, light sensitivity, and sound sensitivity. This is the 4-to-72-hour phase.
Postdrome, sometimes called the migraine hangover, follows the headache and can last anywhere from a few hours to two full days. Common postdrome symptoms include fatigue, body aches (especially a stiff neck), brain fog, difficulty concentrating, dizziness, lingering light or sound sensitivity, and mood changes ranging from mild depression to an unusual sense of euphoria. Many people describe feeling “washed out” during this phase, even though the pain is gone.
When you add all four phases together, a single migraine episode can realistically span five or six days from the first prodrome symptom to the end of postdrome recovery. That total duration is something many people with migraine know intuitively but rarely see acknowledged.
When a Migraine Exceeds 72 Hours
A migraine that lasts longer than 72 hours without meaningful relief is classified as status migrainosus. The pain is unremitting (brief breaks from medication or sleep of up to 12 hours don’t reset the clock) and the symptoms are debilitating. This is considered a complication of migraine, not just a long attack, and it typically requires medical intervention beyond what you’d use at home. If your migraine has persisted past the three-day mark with severe, unrelenting pain, it’s worth seeking urgent care.
Episodic vs. Chronic Migraine
How long individual attacks last is a separate question from how often they occur. Episodic migraine means you get attacks periodically, with stretches of normal days in between. Chronic migraine is defined as headache on 15 or more days per month for more than three months, with at least 8 of those days having migraine features. At that frequency, the line between “recovering from the last attack” and “heading into the next one” can blur, and people with chronic migraine often describe feeling like they’re never fully between episodes.
Chronic migraine doesn’t necessarily mean each individual attack lasts longer. It means attacks come so frequently that they dominate your month. The distinction matters because chronic migraine is managed differently, with a greater emphasis on preventive treatments rather than just treating each attack as it comes.
What Makes Attacks Last Longer
Several factors influence whether your migraines tend toward the shorter or longer end of that 4-to-72-hour window. Dehydration is one of the more straightforward ones: women who drank less water reported longer headache duration, higher pain intensity, and more disability from their migraines. Staying well-hydrated won’t prevent every attack, but it can shorten the ones you do get.
Treating early matters. Taking medication at the first sign of a migraine, rather than waiting to see if the pain builds, generally results in faster resolution. Once a migraine is fully established, it becomes harder to interrupt. The specific medication varies by person, but the timing principle is consistent: earlier treatment means shorter attacks.
Behavioral approaches also play a role over time. Cognitive behavioral therapy, biofeedback, and structured relaxation training have all been shown to reduce migraine severity, including attack duration, in controlled studies. These aren’t quick fixes for a migraine in progress, but they can change the pattern over months by addressing stress responses and pain processing.
Sleep disruption, high stress, and hormonal fluctuations (particularly around menstruation) are all associated with longer, more intense attacks. You can’t control all of these, but recognizing which ones apply to you helps explain why some attacks resolve in hours while others drag on for days.
