Sinus Headache or Migraine? How to Tell the Difference
Pressure across the forehead and cheeks feels like a sinus problem, so that is usually what it gets treated as. A good number of those headaches turn out to be migraine, which is why they keep coming back.
Many people who call their headache a sinus headache may actually be experiencing migraine, especially when the pain keeps recurring, worsens with activity, or is associated with nausea, light sensitivity or sound sensitivity. Sinus-related headache is more likely when facial pressure occurs along with thick nasal discharge, fever, reduced smell, blocked nose, or symptoms lasting more than 7 to 10 days. Migraine can also cause nasal symptoms, which is why recurrent sinus headaches should not be treated repeatedly with antibiotics or painkillers without a proper evaluation.
Headache around the forehead, cheeks or eyes is one of the most common reasons patients suspect sinusitis. In Chennai, this is especially common when headache occurs along with blocked nose, allergy symptoms, AC exposure or weather changes. But not every headache felt over the sinus area is caused by sinus disease.
The treatment is very different. Sinusitis may need nasal treatment, allergy control, endoscopic assessment or, in selected cases, sinus-directed treatment. Migraine needs headache-specific management and sometimes neurology input. Getting the diagnosis right prevents repeated cycles of temporary treatment.
Why sinus headache and migraine are often confused
The forehead, cheeks, nose and eyes share overlapping nerve pathways. Pain from migraine may be felt in the same areas where patients expect sinus pain. At the same time, sinus inflammation can genuinely cause facial pressure and headache.
The confusion increases because migraine can sometimes produce sinus-like symptoms. A migraine attack may be accompanied by nasal congestion, watery eyes, runny nose or pressure around the eyes. When this happens, patients naturally assume the sinuses are the problem.
On the other hand, true sinusitis usually has nasal features in addition to pain. These include thick discharge, reduced smell, fever, blocked nose, postnasal drip or symptoms that persist beyond a usual viral cold.
Quick symptom guide
| Feature | More suggestive of sinusitis | More suggestive of migraine |
|---|---|---|
| Pain location | Forehead, cheeks, around eyes with nasal symptoms | One side of head, forehead, temples, around eyes; may shift sides |
| Nasal discharge | Thick, yellow or green, foul-smelling, or postnasal drip | May have clear runny nose or congestion during attack |
| Smell | Reduced smell is common in sinus disease | Smell sensitivity may occur; reduced smell is less typical |
| Associated symptoms | Fever, blocked nose, facial pressure, cough or postnasal drip | Nausea, vomiting, light sensitivity, sound sensitivity, worsening with activity |
| Duration | Often several days; acute symptoms may last beyond 7 to 10 days | Typically hours to 1 to 3 days; may recur in attacks |
| Treatment response | Improves when sinus, allergy or nasal obstruction is treated | May not improve with sinus medicines or antibiotics |
What a sinus-related headache usually feels like
Sinus-related headache is usually not just headache alone. It is more likely when headache or facial pressure is accompanied by nasal and sinus symptoms. Features that point more toward sinusitis include:
- Blocked nose with thick nasal discharge
- Facial pressure over the forehead, cheeks or between the eyes
- Reduced or lost sense of smell
- Postnasal drip or cough
- Fever or feeling unwell
- Symptoms lasting more than 7 to 10 days
- Symptoms worsening after initially improving
- Recurrent episodes associated with nasal allergy or infections
Patients may feel heaviness when bending forward. However, this symptom alone does not prove sinusitis, because migraine can also worsen with movement or bending.
What migraine usually feels like
Migraine is not just a bad headache. It is a neurological condition that can cause recurring attacks with head pain and other symptoms. Migraine is more likely when headache is associated with:
- Throbbing or pulsating pain
- Pain that worsens with routine activity
- Nausea or vomiting
- Sensitivity to light
- Sensitivity to sound
- Need to rest in a quiet or dark room
- Recurrent similar attacks
- Possible aura, such as visual disturbance, tingling or speech difficulty before the headache
Some migraine patients also develop nasal congestion, watering from the eyes or a runny nose during an attack. This is one reason migraine is frequently mistaken for sinus headache.
Can allergy trigger headache?
Yes, allergy can contribute to headache in more than one way. Nasal allergy can cause congestion, turbinate swelling, postnasal drip and poor sleep. These can make the head feel heavy and uncomfortable.
Allergy may also coexist with migraine. In such patients, dust, AC exposure, poor sleep, strong smells or weather change may trigger both nasal symptoms and headache. Treating the nasal allergy may reduce one trigger, but migraine may still need separate management if typical migraine features are present.
When headache with blocked nose needs ENT evaluation
An ENT evaluation is useful when headache is repeatedly labelled as sinus but keeps coming back, or when nasal symptoms are prominent. You should consider seeing an ENT doctor if you have:
- Headache with persistent blocked nose
- Facial pressure with thick nasal discharge
- Reduced smell
- Repeated sinus infections
- One-sided nasal blockage
- Postnasal drip or chronic throat clearing
- Ear fullness along with nasal symptoms
- Snoring or mouth breathing with nasal obstruction
- No lasting relief despite repeated cold or sinus medicines
An ENT assessment helps check whether there is allergic rhinitis, sinusitis, deviated nasal septum, turbinate swelling, nasal polyps, Eustachian tube dysfunction or another nasal cause contributing to symptoms.
What happens during evaluation?
Your ENT doctor will ask about the pattern of headache and nasal symptoms. Important details include how often the headache occurs, how long it lasts, whether it is one-sided, whether it worsens with activity, and whether there is nausea, light sensitivity or sound sensitivity.
The nose, throat and ears are examined. If sinus disease or nasal obstruction is suspected, nasal endoscopy may be advised. This is a brief in-clinic procedure using a thin camera to examine the inside of the nose.
Nasal endoscopy can help identify swelling, discharge, polyps, deviated septum, turbinate enlargement or sinus drainage problems. A CT scan is not needed for every headache. It is usually considered when sinusitis is suspected, symptoms are recurrent or treatment planning requires more detail.
When neurology input may be needed
If the symptom pattern is more suggestive of migraine, your ENT doctor may advise headache-directed treatment or referral to a neurologist, especially if attacks are frequent, disabling, associated with aura, or not responding to usual measures.
This does not mean the ENT evaluation was unnecessary. It helps avoid missing nasal or sinus disease and also prevents unnecessary sinus treatment when the main issue is migraine.
