How do I know if my headache is a migraine?

A headache is likely a migraine if it causes moderate to severe throbbing pain on one side of the head, worsens with physical activity, and is accompanied by nausea or sensitivity to light and sound, and it lasts 4 to 72 hours without treatment.

Can a tension headache turn into a migraine?

Tension headaches and migraines are distinct conditions, and one does not directly convert into the other. However, frequent unmanaged tension headaches can coexist with migraines in the same person, and high stress levels can trigger both conditions.

Why are migraines worse than regular headaches?

Migraines set off a complex chain of neurological changes: the trigeminal nerve gets activated, serotonin levels are thrown off balance, and CGRP gets released, and all of that together is what drives the intense, drawn-out pain. Add in the nausea, vomiting, and light sensitivity that tend to tag along, and it's easy to see why migraines can be so much more debilitating than other types of headaches.

Can sinus problems cause migraines?

Sinus infection can trigger migraines in susceptible individuals. True sinus headaches caused by acute sinusitis are accompanied by fever, thick nasal discharge, and facial swelling, which are absent in migraines.

Do migraines always cause one-sided head pain?

Not necessarily. While pain on one side is the most common pattern with migraines, some people do experience it on both sides. When it comes to diagnosis, the presence of nausea, sensitivity to light, and how much the headache is affecting daily functioning tends to carry more weight than where exactly the pain is located.

Migraine vs Headache: How Doctors Tell the Difference

Migraine vs Headache: How to Tell the Difference?

Migraines and headaches get mixed up all the time, but they're genuinely two different things. Migraine is its own neurological condition and it stands apart from your typical headache in how it feels, how long it sticks around, how intense it gets, and what's actually causing it. The World Health Organization (2023) identifies headache disorders as some of the most common neurological conditions in the world, with tension headaches and migraines topping the list. Knowing the difference between the two really matters, it's what leads to the right diagnosis and, ultimately, the right treatment.

What Is the Difference Between a Migraine and a Headache?

A headache is really just a broad term for any pain felt in the head or neck area. A migraine, on the other hand, is a specific neurological condition where head pain is just one piece of a much bigger picture driven by complex shifts in brain chemistry, nerve activity, and how blood vessels behave.

Key Distinguishing Features

Pain quality: Headaches typically cause pressing or tightening pain on both sides of the head. Migraines cause moderate to severe throbbing or pulsating pain, usually on one side
Associated symptoms: Headaches rarely cause nausea, vomiting, or significant light and sound sensitivity. Migraines almost always involve one or more of these associated symptoms
Physical activity: For most headaches, everyday movement like walking or climbing stairs won't make things worse. With migraines though, even light physical activity tends to intensify the pain.
Duration: Tension headaches usually clear up within 30 minutes to a few hours, whereas a migraine attack can last anywhere from 4 to 72 hours if left untreated.
Functional impact: Most everyday headaches allow you to carry on fairly normally, while migraines often make it difficult to function at all. Migraines frequently prevent normal activities and can be completely disabling during an attack

Types of Headaches and How They Differ From Migraines

Tension Headache

Tension headache is the most common headache type, affecting up to 78% of the general population at some point in their lives, according to the WHO (2023).

Pain: A mild to moderate pressure or tightening sensation; many people describe it as a band wrapped tightly around the head, with both sides feeling equally affected.
Other symptoms: There might be some mild sensitivity to light or sound, but nausea and vomiting don't tend to feature
Duration: Anywhere from 30 minutes to several hours, though in chronic cases it can drag on for up to 7 days
Triggers: Stress, sitting or standing with poor posture, straining your eyes, and not drinking enough water
Key difference from migraine: Tension headaches do not worsen with physical activity, do not cause nausea, and do not involve throbbing one-sided pain

Cluster Headache

Cluster headaches are rare but extremely severe headaches occurring in cyclical patterns or clusters.

Pain: Intense, one-sided pain focused around or behind one eye, often described as a burning or piercing sensation
Other symptoms: Watering and redness of the eye, a blocked nose, a drooping eyelid, and a sense of restlessness - all on the same side as the pain
Duration: Each attack can last anywhere from 15 minutes to 3 hours, and they can strike up to eight times a day during a cluster period
Key difference from migraine: Cluster headaches cause autonomic symptoms (automatic nervous system responses) such as tearing and nasal congestion on the same side as the pain, which are absent in migraines. Cluster headache sufferers are typically restless during attacks, while migraine sufferers prefer to lie still

Sinus Headache

Sinus headaches happen when the sinuses, the air-filled spaces behind your forehead, cheeks, and eyes become inflamed or infected.

Pain: A deep, constant pressure or aching feeling in the forehead, cheekbones, or behind the eyes
Other symptoms: A blocked nose, thick nasal discharge, fever, and some swelling around the face
Duration: It sticks around for as long as the underlying sinus infection or inflammation is still present
How it differs from migraine: A true sinus headache will come with fever, thick discharge from the nose, and tends to feel worse when you bend forward. Migraines are sometimes misdiagnosed as sinus headaches because some symptoms can overlap but migraines won't cause a fever or that thick nasal discharge

Medication Overuse Headache

Medication overuse headache (MOH) develops when acute pain relievers are taken more than 10 days per month, causing the brain to become dependent on medication and generating rebound headaches.

Pain: A dull, persistent headache that tends to feel worse in the morning but eases off temporarily after taking pain relief
Other symptoms: Nausea, restlessness, trouble concentrating, and feeling irritable
Duration: Present on most days of the month, with little to no real break in between
Key difference from migraine: Medication overuse headache is directly linked to frequent medication use and improves with supervised medication withdrawal, unlike primary migraine

Migraine vs Common Headache Types: Quick Reference

How Do Doctors Tell Migraines Apart From Other Headaches?

Doctors use a structured clinical approach to distinguish migraines from other headache types accurately.

Clinical History

oing through where the pain is, what it feels like, how bad it gets, how long it lasts, and how often it happens
Checking for any symptoms that come along with the headache, like nausea, sensitivity to light, or any changes in vision
Finding out whether any warning signs, like an aura, show up before the headache kicks in
Looking into personal triggers, whether there's a family history of migraines, and how much the headaches are affecting everyday life

The ID Migraine Screening Tool

The ID Migraine is a validated three-question screening tool used by doctors to identify migraines quickly.

Have your headaches stopped you from going about your normal day for a day or more over the last 3 months?
Do you feel nauseous or sick to your stomach when a headache comes on?
Does light feel uncomfortable or bothersome when you're dealing with a headache?

Two or more positive answers have a sensitivity of 81% and specificity of 75% for migraine diagnosis, according to Neurology (2003).

Neurological Examination

A thorough neurological examination assesses reflexes, cranial nerve function, balance, and coordination
A normal neurological examination alongside a consistent headache history supports a primary headache disorder such as migraine
Abnormal neurological findings prompt further investigation with imaging

When Should You See a Doctor?

Headaches are occurring more than 4 days per month
Headache pattern has changed significantly in frequency or severity
Over-the-counter medications are not providing adequate relief
Headaches are accompanied by neurological symptoms such as vision changes, weakness, or speech difficulty
A sudden severe headache described as the worst headache of life occurs, requiring immediate emergency evaluation

Conclusion

Migraines and headaches can feel quite different from one another in terms of pain quality, accompanying symptoms, how long they last, and how much they affect daily life. Tension headaches are the most common type and tend to stand apart from migraines because the pain is usually a pressing sensation on both sides of the head, without any nausea and without getting worse when you move around. Cluster headaches and sinus headaches each have their own distinct features that make them fairly different from a typical migraine. Getting the diagnosis right, through a proper clinical history, tools like the ID Migraine screener, and a neurological check, really is the key to finding the right treatment and avoiding a lot of unnecessary suffering.
