Sinus Headache: Is It Really Sinuses? Causes and Relief

What is a sinus headache?

A sinus headache is pain caused by inflammation or infection of the sinuses (rhinosinusitis). The pain is felt as pressure around the cheeks, eyes, nose bridge or forehead and typically worsens when you bend forward. By definition, it appears together with nasal symptoms: congestion, thick discoloured mucus, reduced smell and sometimes fever.

The International Headache Society states that headache attributed to acute rhinosinusitis occurs with these nasal features and resolves when the sinus condition resolves. When these features are absent, the headache is probably something else.

Sinus headache or migraine?

Throbbing pain, nausea, light or sound sensitivity point towards migraine.
Recurrent attacks lasting hours to days, with or without clear nasal infection, suggest migraine.
Watery eyes, a runny nose and facial pressure can occur in migraine and cluster headache (due to the same nerve pathway), which is why migraine is so often mistaken for sinus disease.
Fever, thick yellow-green discharge for 10 days or more and pain that gets worse when you bend over point towards sinusitis.
Band-like pressure around the head without nasal symptoms suggests a tension-type headache.
In one well-known study of people who believed they had sinus headaches, nearly nine in ten met the criteria for migraine.

Typical symptoms of sinusitis-related headache

Facial pain or pressure over cheeks, forehead or around the eyes.
Blocked or stuffy nose and thick yellow or green mucus.
Reduced sense of smell or taste.
Pain in the upper teeth and bad breath.
Fever, tiredness, cough (worse at night).
Pain that worsens when you bend forward or lie down.

Self-care for sinus pain

Saline rinse or spray to clear mucus.
Steam inhalation or a hot shower.
Warm compress on the face.
Drinking enough fluids and resting.
Paracetamol or ibuprofen as directed for pain.
A decongestant spray for up to 3–5 days if suitable.

Medical treatment

If a sinus infection is likely bacterial (symptoms longer than 10 days, or worsening after initial improvement, or severe features), your doctor may prescribe an antibiotic. For allergic or chronic inflammation, nasal steroid sprays, allergy treatment and sometimes oral steroids are used. If the headache is migraine, treatment shifts to migraine-specific medicines (such as triptans) and preventive strategies, and over-the-counter decongestants will not help.

Medication overuse headache can result from taking painkillers more than 10–15 days a month, so avoid constant use.

Triggers to watch for

Stress, poor or irregular sleep, skipped meals and dehydration.
Hormonal changes and some foods or alcohol (red wine in particular).
Weather and barometric changes.
Strong smells and smoke.
A headache diary for a few weeks helps identify patterns and is useful at your appointment.

When an ENT assessment helps

An ENT doctor can examine the nose with a small flexible camera (nasal endoscopy) to look for pus, polyps, swelling or a deviated septum, and order a CT scan when chronic or complicated sinus disease is suspected. A normal examination and scan make migraine or tension-type headache more likely, and you may then be referred to a neurologist. Imaging is not needed for every headache.

Three common situations

Facial pain, thick green mucus and fever after a cold, 12 days in: likely acute bacterial sinusitis; see a doctor to consider treatment.

Recurrent “sinus headaches” with nausea and light sensitivity: probably migraine; talk to your doctor about migraine treatment.

Facial pressure each spring with sneezing and itchy eyes: consider allergic rhinitis and a treatment plan.

Medication overuse and rebound headache

People who think they have a sinus headache often take painkillers or decongestants frequently. Using simple painkillers on 15 or more days a month, or combination painkillers and triptans on 10 or more days, can cause medication overuse headache, in which headaches become more frequent and persistent. Likewise, decongestant sprays used for more than 3–5 days can cause rebound congestion. If you need medicine most days, speak to your doctor: a correct diagnosis and a preventive plan usually work better than more tablets.

Key points to remember

Not every facial pressure headache is a sinus problem. Look for nasal symptoms and fever; if you have throbbing pain, nausea or light sensitivity, think migraine. Getting the right diagnosis avoids unnecessary antibiotics and decongestants. Consult your doctor or an ENT specialist if headaches recur or are severe.

Questions about sinus headaches

These answers are general information and do not replace an examination or individual medical advice.

How do I know if my headache is from my sinuses?

If you also have a blocked nose, thick discoloured discharge, reduced smell or fever, and pain that worsens when bending forward, sinuses are likely. Without those features, migraine is more likely.

Can migraine feel like a sinus headache?

Yes. Migraine often causes facial pressure, a stuffy nose and watery eyes and is commonly mistaken for sinus headache.

How long does a sinus headache last?

Until the sinus inflammation settles, usually 7–10 days with a cold.

What is the best medicine for a sinus headache?

Simple pain relievers, saline rinses and, in some cases, a nasal steroid. Decongestants help only short-term and not if it is migraine.

Do I need a CT scan?

Not usually. It is considered for chronic or complicated sinus disease.

When is it an emergency?

Sudden severe headache, stiff neck, confusion, vision change or swelling around the eye need urgent care.
