Migraine vs Headache: How to Tell the Difference

Most people have experienced a headache at some point. But if you have ever been flattened by a throbbing, nauseating, light-sensitive episode that put you in bed for hours, you already know that not all head pain is the same.

The words migraine and headache are often used interchangeably, but they are not the same thing. Understanding the difference matters because the causes are different, the treatments are different, and in some cases, getting the wrong treatment can actually make things worse.

This guide breaks down what separates a migraine from a headache, how to identify which one you are experiencing, and what to do about it.

What Is a Headache?

A headache is a broad term for any pain or pressure felt in the head, scalp, or neck. Headaches are extremely common and most are not a sign of anything serious.

They are generally classified as either primary, meaning the headache itself is the condition, or secondary, meaning it is a symptom of something else such as an infection, dehydration, or injury.

The three most common primary headache types are:

1. Tension headache
   The most common type. It produces a dull, pressing sensation that feels like a tight band around the head, affecting both sides. It is often linked to stress, poor posture, eye strain, or dehydration. Most people can continue with their day and find relief with over-the-counter pain medication.
   
2. Sinus headache
   Pain and pressure around the forehead, cheeks, and bridge of the nose, usually occurring alongside congestion, a blocked nose, or a respiratory infection. True sinus headaches are less common than people think and are often misidentified.
   
3. Cluster headache
   A less common but very severe type of headache that causes intense, piercing pain around or behind one eye. Cluster headaches tend to come in cycles, occurring multiple times a day over several weeks before going into remission. They are often accompanied by eye redness, watering, nasal congestion, and restlessness on the affected side. Unlike migraines, people with cluster headaches often feel agitated rather than wanting to lie still.

What Is a Migraine?

A migraine is not simply a severe headache. It is a neurological condition involving complex changes in brain activity and pain-processing pathways that can produce symptoms extending far beyond head pain.

According to the International Classification of Headache Disorders (ICHD-3), migraine is characterised by recurrent attacks of moderate to severe, often one-sided, throbbing head pain that worsens with physical activity and is commonly accompanied by nausea, sensitivity to light, or sensitivity to sound.

Migraines affect approximately 1 in 7 adults and are among the leading causes of disability worldwide, particularly in people under the age of 50.

A migraine attack can occur in up to four distinct phases, although not everyone experiences every stage.

Prodrome

The prodrome phase can begin hours or even days before the headache itself. It often acts as an early warning sign that a migraine attack is developing.

Common symptoms include:

• Fatigue
• Mood changes
• Food cravings
• Increased yawning
• Difficulty concentrating
• Neck stiffness

Aura

Aura affects roughly one-third of people with migraine and typically occurs before or during the headache phase. These symptoms are usually temporary and develop gradually over several minutes.

Common aura symptoms include:

• Flashing lights
• Zigzag lines
• Blind spots
• Blurred vision
• Tingling sensations
• Numbness affecting one side of the face or body

Most aura symptoms last between 5 and 60 minutes.

Headache Phase

This is the main stage of a migraine attack and is usually what people associate with migraine.

Symptoms may include:

• Throbbing or pulsating head pain
• Pain affecting one side of the head
• Moderate to severe pain intensity
• Nausea or vomiting
• Sensitivity to light
• Sensitivity to sound
• Symptoms that worsen with physical activity

Many people find relief by resting in a dark, quiet environment until the attack subsides.

Postdrome

Often referred to as the “migraine hangover”, the postdrome phase occurs after the headache resolves and can last for up to 48 hours.

Common symptoms include:

• Fatigue
• Mental fogginess
• Difficulty concentrating
• Low mood
• Feeling emotionally drained

Some people may also experience a temporary sense of relief or mild euphoria following the attack.

Migraine vs Headache: Key Differences at a Glance

Tension Headache	Cluster Headache	Migraine
Pain type	Dull, pressing	Sharp, piercing	Throbbing, pulsating
Location	Both sides	One side, around eye	Usually one side
Duration	30 min to several hours	15 min to 3 hours	4 to 72 hours
Nausea	Rare	Rare	Common
Light sensitivity	Mild	Uncommon	Common
Aura	No	No	In about one third of cases
Activity during attack	Usually able to continue	Restless and agitated	Worsened by movement
Phases before and after	No	No	Prodrome and postdrome common

How to Know If You Are Having a Migraine

According to ICHD-3 criteria, a migraine without aura requires at least two of the following pain characteristics: unilateral location, pulsating quality, moderate to severe intensity, and worsening with routine physical activity. The attack must also be accompanied by nausea or vomiting, or by both photophobia and phonophobia.

Ask yourself:

• Is the pain on one side of your head?
• Is it throbbing or pulsating rather than pressing?
• Does it get worse when you move around?
• Are you nauseated, or do you need to avoid light and sound?
• Does the attack last more than four hours?
• Do you notice warning signs such as fatigue, mood changes, or visual disturbances before the pain begins?

If you answered yes to most of these, what you are experiencing is likely migraine rather than a tension or sinus headache.

When Should You See a Doctor?

Many headaches can be managed at home, but some situations warrant professional assessment.

Book an appointment if:

• You are having headaches more than twice a week
• Over-the-counter medications are regularly needed and not providing adequate relief
• Headaches are disrupting work, sleep, or daily activities
• You suspect you may have migraines but have never been formally diagnosed
• Your headache pattern has changed or become more frequent

Seek urgent care if a headache:

• Comes on suddenly and is the most severe you have ever experienced
• Is accompanied by fever, stiff neck, confusion, or a rash
• Follows a head injury
• Comes with sudden vision loss, weakness, difficulty speaking, or loss of balance
• Occurs in someone over 50 with no previous headache history

Final Thoughts

A headache and a migraine are not the same thing, and treating them as if they are can mean spending years managing symptoms without ever addressing the real cause. Migraine is a distinct neurological condition that responds to specific treatments and is increasingly well understood by medical science.

If your head pain is frequent, debilitating, or coming with nausea, light sensitivity, or visual disturbances, it is worth getting a proper diagnosis. The right treatment can make a significant difference to how often attacks occur and how manageable they are when they do.
