Migraine vs Headache: How to Tell the Difference and Why It Matters

Why This Distinction Matters

If you’ve ever dismissed a severe headache as “just a headache,” you might be missing a migraine diagnosis. Studies show that approximately 50% of people who meet the diagnostic criteria for migraine have never been properly diagnosed [1]. They treat their episodes with over-the-counter pain relievers, miss work, push through the nausea, and never access the migraine-specific therapies that could dramatically reduce their suffering.

The difference between a headache and a migraine is not just about severity. A migraine is a neurological disease involving abnormal brain activity, neurotransmitter changes, and a cascade of inflammatory events. A tension headache is primarily a pain condition involving muscle tension and peripheral sensitization. They require different treatment strategies, different prevention approaches, and carry different long-term implications [2].

The Key Differences at a Glance

The International Classification of Headache Disorders (ICHD-3), published by the International Headache Society, provides standardized diagnostic criteria that clinicians use worldwide [3]. Here’s how the most common types compare:

Migraine Without Aura

• Location: Unilateral (one side) in about 60% of attacks, though it can be bilateral
• Quality: Pulsating or throbbing
• Intensity: Moderate to severe (interferes with daily activities)
• Duration: 4-72 hours (untreated)
• Activity effect: Worsened by routine physical activity (walking, climbing stairs)
• Associated symptoms: At least one of nausea/vomiting OR both photophobia and phonophobia
• Minimum episodes for diagnosis: 5 attacks meeting the above criteria

Tension-Type Headache

• Location: Bilateral (both sides), often described as a band around the head
• Quality: Pressing or tightening (non-pulsating)
• Intensity: Mild to moderate (annoying but does not prevent activities)
• Duration: 30 minutes to 7 days
• Activity effect: Not worsened by routine physical activity
• Associated symptoms: No nausea or vomiting, may have either photophobia or phonophobia (but not both)
• Minimum episodes for diagnosis: 10 attacks meeting the above criteria [3]

Other Headache Types You Should Know

Cluster Headache

Cluster headaches are sometimes called “suicide headaches” because the pain intensity is among the worst known to medicine. They are distinct from both migraines and tension headaches [4].

Key features:

• Location: Strictly unilateral, centered around one eye or temple
• Quality: Excruciating, boring, or piercing
• Duration: 15 minutes to 3 hours per attack
• Frequency: 1-8 attacks per day during a cluster period, which typically lasts 6-12 weeks
• Autonomic symptoms: Tearing, redness of the eye, nasal congestion or runny nose, drooping eyelid, and facial sweating (all on the same side as the pain)
• Behavior: Unlike migraine sufferers who want to lie still, cluster headache patients are agitated and restless during attacks

Cluster headaches affect about 0.1% of the population and are 3-4 times more common in men. They follow a circadian pattern, often striking at the same time each day, frequently waking patients 1-2 hours after falling asleep [5].

Sinus Headache

Here’s something most patients don’t know: the vast majority of self-diagnosed “sinus headaches” are actually migraines. A landmark study published in Archives of Internal Medicine found that 88% of patients with a history of “sinus headache” actually met ICHD criteria for migraine [6].

The confusion arises because migraines can cause nasal congestion, facial pressure, and watery eyes through activation of the trigeminal autonomic reflex. True sinus headaches occur only with acute bacterial sinusitis and are accompanied by purulent (thick, discolored) nasal discharge and fever.

If your “sinus headaches” are recurrent, worsen with bending over, and respond to triptans or come with light sensitivity, they are almost certainly migraines.

Cervicogenic Headache

Pain originating from the cervical spine (neck) that refers to the head. These headaches are strictly one-sided, triggered by neck movement or sustained postures, and associated with reduced range of motion in the cervical spine. They are common in people with neck injuries, poor posture, or cervical disc disease [7].

Migraine-Specific Features That Headaches Don’t Have

Aura

About 25-30% of migraine patients experience aura: a transient neurological disturbance that typically precedes the headache phase by 5-60 minutes. The most common form is visual aura (zigzag lines, blind spots, shimmering crescents), but it can also manifest as tingling, numbness, or difficulty finding words [8].

Aura is caused by cortical spreading depression, a slow wave of neuronal depolarization that moves across the brain surface. No other primary headache type produces aura. If you experience aura, you have migraine.

Prodrome and Postdrome

Migraine is actually a multi-phase neurological event. Many patients experience prodromal symptoms 24-48 hours before the headache: food cravings (especially for sweets or carbohydrates), mood changes, excessive yawning, neck stiffness, increased urination, or fatigue [9].

After the headache resolves, a postdrome phase (“migraine hangover”) can last another 24-48 hours, characterized by cognitive difficulty, fatigue, mood changes, and sensitivity to head movement. Tension headaches do not have these distinct phases.

Photophobia and Phonophobia

Sensitivity to light and sound during migraine is not simply finding bright lights or loud noises unpleasant. It represents a measurable change in sensory processing. During migraine, the threshold for pain from light and sound drops dramatically due to sensitization of thalamic neurons that relay sensory information [10].

This is why migraine patients retreat to dark, quiet rooms. Tension headache patients may prefer a dimmer environment, but they can typically function in normal lighting and noise levels.

Nausea and Vomiting

Approximately 80% of migraine patients experience nausea and about 30% vomit during attacks. This occurs because the migraine process activates the brainstem’s vomiting center through connections with the trigeminal nucleus caudalis [11]. Nausea also slows gastric motility, which is why oral medications taken during a migraine are often poorly absorbed, making alternative delivery routes (nasal sprays, injections) more effective.

When a Headache Is Actually a Migraine: A Self-Check

A validated screening tool called ID Migraine uses just three questions to identify migraine with 81% sensitivity and 75% specificity [12]. If you answer “yes” to at least two of these three questions about your headaches, there’s a strong probability you have migraine:

1. Has a headache limited your activities for a day or more in the last 3 months?
2. Are you nauseated or sick to your stomach when you have a headache?
3. Does light bother you when you have a headache?

If this sounds like your experience, bring these answers to your doctor. A migraine diagnosis opens the door to treatments that are far more effective than general pain relievers.

Treatment Differences

Tension Headache Treatment

First-line treatment for episodic tension headaches is simple analgesics: acetaminophen, ibuprofen, or aspirin. These work by reducing peripheral pain signaling and prostaglandin production. Non-pharmacological approaches include stress management, physical therapy for the cervical and pericranial muscles, and postural correction [13].

For chronic tension headache (15 or more days per month), low-dose amitriptyline is the most evidence-based preventive medication.

Migraine Treatment

Migraine treatment has been transformed in the past decade. Options now include:

Acute (stopping an attack):

• Triptans: Sumatriptan, rizatriptan, and others. These are serotonin 5-HT1B/1D agonists that constrict dilated blood vessels and block pain transmission in the trigeminal nerve. They are migraine-specific and do not work for tension headaches.
• Gepants: Ubrogepant (Ubrelvy), rimegepant (Nurtec). These block CGRP receptors, targeting the inflammatory peptide that drives migraine pain. They have fewer vascular side effects than triptans.
• Ditans: Lasmiditan (Reyvow). A 5-HT1F agonist that works centrally without vasoconstriction, making it safe for patients with cardiovascular risk factors.

Preventive (reducing attack frequency):

• CGRP monoclonal antibodies: Erenumab (Aimovig), fremanezumab (Ajovy), galcanezumab (Emgality), eptinezumab (Vyepti). Monthly or quarterly injections that reduce migraine days by 50% or more in many patients [14].
• Neuromodulation devices: Non-invasive vagus nerve stimulation, transcranial magnetic stimulation
• Traditional preventives: Beta-blockers (propranolol), anticonvulsants (topiramate), antidepressants (amitriptyline, venlafaxine)

The point is clear: if you have migraine and you’re only taking ibuprofen, you’re managing symptoms with a tool designed for a different condition.

When to See a Doctor

Seek medical evaluation if you experience:

• A sudden, severe headache (“worst headache of my life”) that peaks within seconds to minutes. This requires emergency evaluation to rule out subarachnoid hemorrhage.
• New headache pattern after age 50, which warrants imaging to rule out structural causes including giant cell arteritis.
• Headache with fever, neck stiffness, and altered mental status, which may indicate meningitis.
• Progressive headache worsening over weeks, which may suggest a mass lesion or increased intracranial pressure.
• Headache with new neurological deficits (weakness, numbness, vision changes, speech difficulty) that persist beyond 60 minutes, which requires stroke evaluation.
• Headaches occurring 15 or more days per month, which indicates chronic headache requiring preventive treatment and evaluation for medication overuse headache [15].

Even if your headaches don’t meet these red-flag criteria, any headache pattern that disrupts your work, relationships, or quality of life deserves a proper evaluation. You shouldn’t accept frequent headaches as “just normal.”

Frequently Asked Questions

How can I tell if I have a migraine or a tension-type headache?

The pain patterns differ. Migraines without aura are usually one-sided (about 60% of attacks), pulsating or throbbing, moderate to severe enough to interfere with daily activities, and worsened by routine physical activity. Tension-type headaches are typically bilateral, described as a band or pressing, tightening sensation around the head, mild to moderate, non-pulsating, and not made worse by movement.

Does a migraine always come with an aura?

No. The article notes that aura is present in only about 25 to 30% of migraine patients. When it does occur, it typically involves visual disturbances such as zigzag lines, blind spots, or shimmering crescents, or sensory and speech changes, appearing 5 to 60 minutes before the headache. Many people have migraine without aura.

How long do migraines and tension headaches last?

Untreated migraine attacks last 4 to 72 hours. Tension-type headaches range from 30 minutes to 7 days. Migraine is also described as a multi-phase event, with prodromal symptoms appearing 24 to 48 hours before the headache and a postdrome, or migraine hangover, lasting another 24 to 48 hours.

Could what I think is a sinus headache actually be a migraine?

It is possible. The article reports that 88% of patients with a history of sinus headache actually met the ICHD criteria for migraine. It also notes that roughly 50% of people who meet the diagnostic criteria for migraine have never been properly diagnosed, so misattribution is common.

What treatments are available for each type?

For acute migraine, the article lists triptans (such as sumatriptan and rizatriptan), gepants (ubrogepant, rimegepant), and ditans (lasmiditan). Preventive options include CGRP monoclonal antibodies, which reduce migraine days by 50% or more in many patients, along with beta-blockers, anticonvulsants, and antidepressants. For tension headaches, first-line treatment is simple analgesics such as acetaminophen, ibuprofen, or aspirin, with low-dose amitriptyline being the most evidence-based preventive for chronic cases.

When should a headache prompt me to see a doctor?

The article flags several red flags requiring medical evaluation: a sudden severe headache peaking within seconds (the worst headache of my life), a new headache pattern after age 50, headache with fever, neck stiffness, and altered mental status, progressive worsening over weeks, persistent neurological deficits beyond 60 minutes, and headaches occurring 15 or more days per month.
