Sinus Headache or Migraine? Why Facial Pain Is Often Misdiagnosed

Facial pressure around the cheeks, forehead or eyes is often labelled as sinusitis. In reality, facial pain is one of the most commonly misinterpreted nasal symptoms. Many patients who believe they have recurrent sinus infections actually have migraine, tension-type headache, dental pain, jaw joint problems or a chronic facial pain syndrome.

This matters because the wrong diagnosis can lead to repeated antibiotics, unnecessary nasal sprays, frustration and delay in receiving the right treatment.

At Hampshire ENT Clinics, Mr Tim Biggs and Mr Steve Hayes assess patients with facial pressure, suspected sinusitis and persistent nasal symptoms. The aim is to identify whether the sinuses are truly the cause and to guide patients toward the right treatment pathway.

Quick answer: how do I know if facial pain is sinusitis?

Facial pain is more likely to be sinus-related when it occurs with nasal blockage, discoloured nasal discharge, reduced smell and objective signs of sinus inflammation on nasendoscopy or CT. Facial pain alone, especially with a normal CT scan, is less likely to be caused by sinusitis.

Why sinus headache is overdiagnosed

The sinuses are located around the cheeks, forehead and between the eyes, so it is understandable that facial pressure is blamed on the sinuses. However, migraine commonly causes pain in the forehead, around the eyes and across the face. It can also cause nasal symptoms such as congestion or watering due to activation of nerve pathways.

Patients may therefore experience a genuine headache with nasal symptoms, but the primary problem may still be migraine rather than sinus infection.

Symptoms that support sinusitis

Sinusitis is more likely when facial pressure occurs alongside nasal blockage, thick discharge, post-nasal drip, reduced smell, fever in acute infection, or persistent symptoms lasting more than 12 weeks in chronic sinusitis.

Objective findings matter. Nasendoscopy may show pus, polyps or inflammation. CT may show sinus opacification or blocked drainage pathways.

Symptoms that suggest migraine or non-sinus pain

Migraine may cause one-sided throbbing pain, sensitivity to light, sensitivity to sound, nausea, worsening with movement, visual symptoms or attacks lasting hours to days. Some patients have facial pressure rather than a classic headache.

Mid-facial segment pain can cause pressure across the cheeks and bridge of the nose despite normal nasal examination and normal CT imaging. Dental pain and jaw joint dysfunction can also mimic sinus pain.

Why antibiotics often do not solve the problem

Antibiotics may be appropriate for selected bacterial infections, but they do not treat migraine, nerve-related pain, jaw dysfunction or non-infective facial pain. Repeated antibiotic courses without objective sinus disease can cause side effects and does not address the underlying problem.

A clear diagnosis is therefore important before continuing repeated treatment for “sinus infections”.

How ENT assessment helps

ENT assessment helps determine whether the nose and sinuses are involved. The consultation explores symptom timing, triggers, nasal obstruction, discharge, smell, allergy, dental history, headache features and previous treatment.

Nasendoscopy can examine the nasal cavity and sinus drainage areas. CT imaging may be arranged if chronic sinusitis is suspected or if symptoms are persistent, recurrent or one-sided.

What if the CT scan is normal?

A normal sinus CT is very helpful. It can reassure patients that the sinuses are not the cause of symptoms and allow treatment to focus on migraine, neurology, dental review, jaw joint management or pain pathways.

This is not a dismissal of symptoms. It is a step toward the correct diagnosis.

When sinus surgery helps facial pain

Sinus surgery can help when facial pain is part of proven chronic sinusitis or recurrent acute sinusitis with objective disease on CT or endoscopy. It is less likely to help facial pain when scans are normal and nasal symptoms are absent.

A careful specialist opinion helps avoid unnecessary surgery while identifying patients who genuinely benefit from sinus treatment.

When to book an appointment

Consider ENT review if you have facial pressure with nasal blockage, discharge, reduced smell, recurrent suspected sinus infections, one-sided symptoms, symptoms not improving with treatment, or uncertainty about whether headaches are sinus-related.

Hampshire ENT Clinics offers consultant-led rhinology assessment in Hampshire, with Mr Tim Biggs and Mr Steve Hayes providing specialist nasal and sinus expertise.

Frequently asked questions

Is sinus headache common?

True sinus headache exists, but many headaches labelled as sinus headaches are actually migraine or other facial pain conditions.

Can migraine cause nasal congestion?

Yes. Migraine can produce nasal or eye symptoms, which can make it feel like a sinus problem.

What symptoms make sinusitis more likely?

Nasal blockage, thick discharge, reduced smell and objective inflammation on endoscopy or CT make sinusitis more likely.

Can I have sinus pain with a normal CT scan?

If CT is normal, the sinuses are less likely to be the cause. Other causes such as migraine, dental pain or mid-facial pain should be considered.

Do I need antibiotics for sinus pressure?

Not always. Antibiotics only help selected bacterial infections and are not useful for migraine or non-infective facial pain.

Can dental problems mimic sinus pain?

Yes. Upper tooth disease and jaw problems can cause cheek pressure and may overlap with sinus symptoms.

When is CT useful?

CT is useful when chronic sinusitis, recurrent infections, one-sided symptoms or surgical planning are being considered.

Can sinus surgery cure headaches?

Only if headaches are genuinely related to sinus disease. It is unlikely to help migraine with normal sinus imaging.

Who assesses sinus headache at Hampshire ENT Clinics?

Mr Tim Biggs and Mr Steve Hayes assess patients with suspected sinusitis, facial pressure and nasal symptoms.

Should I see ENT or neurology?

If nasal symptoms are prominent, ENT assessment is sensible. If migraine features dominate or CT is normal, neurology or headache-focused care may be appropriate.
