Sinus Headache vs. Migraine: How to Tell the Difference

Sinus headaches and migraines are often confused — even by people who have experienced headaches for years. Many patients come to us convinced their pain is coming from their sinuses, only to learn later that migraine is the more likely cause.

Understanding the difference matters. Sinus headaches and migraines have different causes, different treatments, and different specialists involved. Below is a clear, clinical guide to help you understand which condition your symptoms most closely match — and when it may be time to see an ENT.

Why sinus headaches and migraines are commonly confused

Both sinus headaches and migraines can cause pain around the eyes, forehead, and face. Nasal congestion, pressure, and even weather sensitivity are often blamed on the sinuses — but these symptoms frequently overlap with migraine.

In clinical practice, true sinus headaches are far less common than people realize. Many patients diagnosed with "recurrent sinus headaches" actually meet criteria for migraine, especially when imaging shows no active sinus infection or inflammation.

This overlap is one of the most common reasons headaches are misdiagnosed — and improperly treated — for years.

How a sinus headache usually feels

A true sinus headache is typically associated with active sinus inflammation or infection.

Common sinus headache symptoms include:

• Pressure or fullness in the cheeks, forehead, or between the eyes
• Facial pain that worsens when bending forward
• Thick nasal drainage or congestion
• Reduced sense of smell
• Pain that accompanies or follows a cold, sinus infection, or allergies

Sinus-related pain is often dull, constant, and localized to the affected sinus cavities. It usually improves as the underlying sinus condition resolves.

How a migraine usually feels

Migraine is a neurological condition, not simply a bad headache. Pain is only one component of a much broader symptom pattern.

Migraine symptoms commonly include:

• Moderate to severe head pain, often throbbing or pulsating
• Pain on one side of the head (though it can be bilateral)
• Sensitivity to light, sound, or smells
• Nausea or vomiting
• Visual changes or aura
• Fatigue, brain fog, or neck stiffness

Many people are surprised to learn that migraines can also cause nasal congestion, facial pressure, and weather sensitivity — features that often lead patients to assume the pain is sinus-related when it is not.

Key differences between sinus headache and migraine

While symptoms overlap, several features can help distinguish the two:

Sinus headache:

• Usually follows a respiratory infection or sinus flare
• Associated with thick nasal discharge and facial tenderness
• Pain is pressure-like and localized
• Improves with treatment of sinus inflammation

Migraine:

• Often occurs without infection
• Accompanied by light or sound sensitivity, nausea, or aura
• Pain may be throbbing and temporarily disabling
• Can last hours to days and recur predictably

If headaches recur despite antibiotics, decongestants, or normal sinus imaging, migraine becomes far more likely. When imaging does not show sinus inflammation, further evaluation is often needed.

When to see an ENT vs. a neurologist

Knowing which specialist to see can save time and unnecessary treatment.

You may benefit from seeing an ENT if:

• Headaches occur alongside frequent sinus infections
• Symptoms include thick nasal drainage, fever, or persistent congestion
• Imaging shows sinus disease
• Facial pain worsens with sinus pressure changes

You may benefit from neurological evaluation if:

• Headaches are recurrent without infection
• Symptoms include light sensitivity, nausea, or aura
• Pain persists despite sinus treatment
• Headaches interfere with daily functioning

At Exhale Sinus, we often help patients determine whether their symptoms are truly sinus-related or whether migraine is the more likely diagnosis — and guide them toward appropriate next steps.

How we evaluate headache at Exhale Sinus

Our evaluation focuses on clarity, not assumptions. We assess:

• Symptom patterns over time
• Nasal and sinus anatomy
• Prior imaging and treatment response
• Features suggestive of migraine vs. sinus disease

When sinus disease is present, we address it directly. When migraine is more likely, we help patients avoid unnecessary sinus procedures and connect them with the right care pathway.

Frequently asked questions

Can sinus infections cause migraines?Sinus infections can trigger headaches, but migraine is a separate neurological condition. Many people experience both, which adds to the confusion.

Do migraines show up on CT scans?No. CT scans evaluate sinus anatomy and inflammation, not migraine. A normal scan often points away from sinus headache as the cause.

Why do decongestants sometimes help migraines?Some migraines cause nasal congestion as part of the attack. Decongestants may temporarily relieve pressure but do not treat the underlying migraine process.

The bottom line

Not every headache around the face or eyes is a sinus headache. Migraines are frequently mistaken for sinus-related pain, leading to delayed diagnosis and ineffective treatment.

Understanding the difference between sinus headache and migraine is the first step toward getting the right care — and lasting relief.
