how long does migraine headache last

A typical migraine attack lasts between 4 hours and 3 days (72 hours) if untreated. However, the entire episode can span several days when including all of its distinct biological phases.¹²³⁴

The Four Phases of a Migraine Attack

A complete migraine episode typically moves through up to four sequential stages:¹²

• Prodrome (Early Warning Stage): Can start hours to 1 or 2 days before the head pain begins. Symptoms include fatigue, irritability, food cravings, frequent urination, and difficulty concentrating.¹²
• Aura (Sensory Disturbances): Occurs in about one-third of people and lasts from 5 to 60 minutes. It can include visual changes (flashing lights or zig-zag patterns), numbness, tingling, or speech difficulty.¹²
• Headache Phase (Main Attack): Lasts anywhere from 4 to 72 hours. It features moderate-to-severe throbbing pain—often on one side of the head—along with nausea and sensitivity to light, sound, or odors.¹²³⁴⁵
• Postdrome ("Migraine Hangover"): Lasts from a few hours up to 48 hours after the head pain stops. You may feel exhausted, foggy, dizzy, or tender.¹²³⁴

What is Status Migrainosus?

When a migraine attack lasts longer than 72 hours (3 days) continuously, it is clinically known as status migrainosus. This severe, prolonged state often requires medical evaluation or urgent care intervention for specialized medication and rehydration.¹²You can read more about tracking symptoms and warning signs on the American Migraine Foundation or review general guidance via the NHS Migraine Guide.¹²To help tailor this information, let me know:

• How long your current or recent attack has lasted
• Whether you are experiencing aura symptoms
• If you have already tried over-the-counter or prescription treatments

An untreated or unmanaged migraine attack typically lasts anywhere from 4 hours to 3 days (72 hours).¹

However, a full migraine episode involves more than just the head pain phase and progresses through distinct stages:

The Stages of a Migraine Attack

1. Prodrome (Early Symptoms)
   • Timing: Can start hours to 2 days before the head pain begins.
   • What it feels like: Fatigue, mood changes, food cravings, neck stiffness, or frequent yawning.¹
2. Aura (Visual or Sensory Disturbances)
   • Timing: Lasts up to 1 hour (if it goes past an hour, it should be evaluated by a healthcare professional).
   • What it feels like: Seeing flashing lights, zigzag patterns, blind spots, or experiencing tingling/numbness. Not everyone gets an aura.¹
3. Headache Phase (The Main Attack)
   • Timing: Usually lasts 4 hours to 72 hours.
   • What it feels like: Throbbing or pulsing pain (often on one side of the head), accompanied by sensitivity to light and sound, nausea, or vomiting.¹
4. Postdrome ("Migraine Hangover")
   • Timing: Can linger for 24 to 48 hours after the main headache subsides.
   • What it feels like: Drained, washed-out, sore, or struggling to concentrate.¹

When to Seek Immediate Medical Help

According to the NHS Migraine Guidance, you should contact NHS 111 or seek urgent medical attention if:¹

• Your migraine attack lasts longer than 72 hours.
• Aura symptoms last longer than 1 hour.
• You experience a sudden, severe "thunderclap" headache (like a sudden hit to the head).
• The headache is accompanied by a high fever, stiff neck, confusion, double vision, or weakness/paralysis on one side of your body.¹

If you'd like, let me know:

• How long your current or recent headache has lasted
• Whether you are experiencing any other symptoms like aura or nausea

I can help you figure out if it's time to reach out to a GP or pharmacist.

A migraine headache typically lasts 4 to 72 hours (4 hours to 3 days) if left untreated.

However, the duration varies from person to person and from one migraine attack to another.

How long do the different stages last?

When should you be concerned?

Seek urgent medical attention if:

• Your headache is sudden and extremely severe (the worst headache of your life).
• You experience weakness, confusion, difficulty speaking or loss of vision.
• You have a headache with fever, stiff neck or a rash.
• A migraine lasts longer than 72 hours. This may be status migrainosus, a prolonged migraine that may need medical treatment.

A few questions to understand your situation:

1. How long have you had the headache — hours, 1–2 days, or longer?
2. Is the pain on one side of your head or both sides?
3. Do you have nausea, sensitivity to light, or sensitivity to sound?
4. Is this your first migraine, or have you experienced it before?

I can help you understand whether your symptoms sound like a typical migraine or whether you should seek medical attention.
