A typical migraine headache lasts between 4 and 72 hours, but the full experience of a migraine attack, from the earliest warning signs to complete recovery, can stretch across several days. How long yours lasts depends on factors like your age, hormonal patterns, and whether you treat the attack early.
The Headache Phase: 4 to 72 Hours
The window most people care about is the headache itself. For adults, this intense phase typically runs from several hours up to three days. Some attacks resolve in an afternoon, while others persist through an entire weekend. The pain usually builds on one side of the head, often with nausea, light sensitivity, or both. Treating early in this window, before pain becomes severe, tends to shorten it significantly.
If your headache phase consistently lasts longer than 72 hours, that crosses into a condition called status migrainosus. This is considered a medical emergency because the prolonged inflammation and dehydration from days of nausea can create compounding problems. A healthcare provider can help break the cycle with treatments you can’t access at home.
The Full Attack Lasts Longer Than You Think
Migraine is more than a headache. A complete attack moves through up to four distinct phases, and the total duration from start to finish often surprises people who think of migraine as a few bad hours.
Prodrome
Hours or even days before the headache arrives, your body starts sending signals. You might notice food cravings, neck stiffness, unusual fatigue, mood changes, or frequent yawning. This phase can last several hours to several days, and recognizing it gives you a head start on treatment. Many people don’t connect these symptoms to migraine until they learn to track them.
Aura
About one in four people with migraine experience aura, which typically involves visual disturbances like zigzag lines, blind spots, or flashing lights. Some people get tingling in their hands or face, or have difficulty finding words. Aura commonly lasts 10 to 30 minutes, develops gradually over at least 5 minutes, and resolves within an hour. In roughly 20% of people who get aura, it can last longer than 60 minutes.
Headache
This is the phase described above: several hours to three days of throbbing, often one-sided pain with sensitivity to light, sound, and sometimes smell.
Postdrome (the Migraine Hangover)
After the headache fades, most people don’t feel normal right away. The postdrome phase brings fatigue, brain fog, body soreness, and difficulty concentrating. It can last anywhere from a few hours to two full days. During this time, pushing through strenuous activity can actually trigger another attack, so your body genuinely needs the recovery time. If these non-headache symptoms persist beyond 48 hours, it’s worth mentioning to your provider.
Add it all up and a single migraine attack can span anywhere from about half a day to nearly a week when you account for every phase.
Migraine Duration in Children
Children’s migraines tend to be shorter than adults’, which has historically made them harder to diagnose. In one study of pediatric patients, about half had headaches lasting under 4 hours, and nearly 14% had headaches that resolved in less than 2 hours. The formal diagnostic criteria were originally built around adult patterns, which means many children with genuine migraine don’t meet the standard 4-hour minimum. Researchers have suggested that headaches lasting as little as 2 hours in children under 15 should still qualify, and removing the strict duration requirement would allow roughly 80% of affected children to receive a proper diagnosis instead of just 34%.
Menstrual Migraines Often Last Longer
Migraines tied to hormonal shifts around menstruation tend to be more severe and longer-lasting than other migraine episodes. They can begin up to two days before your period starts and persist for three days into it. That’s a potential five-day window of vulnerability each cycle. The drop in estrogen that triggers these attacks also makes them more resistant to standard treatments, so they’re more likely to run their full course.
When Migraines Happen Too Often
Duration of a single attack is one concern. Frequency is another. If you have headaches on 15 or more days per month for more than three months, with at least 8 of those days having migraine features, that meets the international criteria for chronic migraine. At that point, the question shifts from “how long does one attack last” to “how many days per month am I actually headache-free.” Chronic migraine affects daily functioning in ways that episodic migraine doesn’t, and it typically calls for preventive treatment rather than just treating attacks as they come.
What Affects How Long Yours Last
Several factors influence whether your migraines tend toward the shorter or longer end of the spectrum:
- Treatment timing: Taking medication early in the headache phase, ideally within the first hour, consistently shortens attacks compared to waiting until pain peaks.
- Sleep: Many people find that sleep ends or significantly shortens a migraine. Attacks that start in the evening sometimes resolve overnight.
- Trigger load: A migraine set off by multiple triggers at once (poor sleep plus stress plus skipped meals, for example) tends to be more intense and longer-lasting.
- Hormonal factors: Menstrual migraines and migraines during perimenopause are often more prolonged than attacks at other times.
- Medication overuse: Frequently using pain relievers for migraine (more than 10 to 15 days per month, depending on the type) can paradoxically increase both the frequency and duration of attacks over time.
Tracking your attacks with a headache diary, noting when they start, when they peak, and when you feel fully recovered, gives you a clearer picture of your personal pattern and helps a provider determine whether your migraines need a different treatment approach.
