Sinus Headache Treatment and How to Tell It From a Migraine

How to Treat a Sinus Headache

To relieve a genuine sinus headache, the aim is to clear the congestion behind the pain, not just numb the ache. Rinse the nose with a saline spray or sinus rinse, breathe in steam from a bowl of hot water or a warm shower, and stay well hydrated to thin the mucus. A short course of a decongestant (oral pseudoephedrine, kept behind the pharmacy counter, or a medicated nasal spray for no more than a few days) can open blocked sinuses, while paracetamol or ibuprofen eases the pain and pressure. If congestion and facial pain drag on for more than about a week, a steroid nasal spray or a GP review may be needed. Ask your pharmacist which combination suits you, and always read the label.

Most 'Sinus Headaches' Are Actually Migraines

This is the part almost everyone gets wrong, so it is worth stating plainly. Multiple studies of people who were convinced they had 'sinus headaches' found that the large majority — commonly reported at around 90% — actually met the diagnostic criteria for migraine or another primary headache. They did not have a sinus infection at all.

The confusion is understandable. Migraines can cause facial pain and pressure over the cheeks and forehead, a stuffy or runny nose, and watery eyes — all of which feel exactly like 'sinus'. The migraine nerve pathways sit right behind the same areas your sinuses occupy, so the brain interprets the pain as coming from the sinuses. If you have been treating recurring 'sinus headaches' with decongestants for years and they never quite work, this is very likely why.

Getting this right matters because the treatments barely overlap. Decongestants and steam do little for a migraine; migraine responds to pain relievers taken early, rest, and sometimes specific migraine medicines. If you would like a full side-by-side breakdown of migraine features, see our guides to migraine vs tension headache and how to treat headaches, which cover migraine-specific treatment in depth.

Sinus Headache vs Migraine: How to Tell Them Apart

What a True Sinus Headache Feels Like

A genuine sinus headache is a symptom of sinusitis — inflammation of the air-filled cavities in the bones around your nose and eyes. When these sinuses become inflamed or infected, they swell, trap mucus, and build up pressure, producing a deep ache across the face. Most sinusitis is triggered by a viral cold and clears on its own; only a minority becomes a bacterial infection.

Common symptoms of sinusitis

• radio_button_uncheckedDeep, constant pressure or pain in the cheeks, forehead, or bridge of the nose
• radio_button_uncheckedPain that worsens when you bend forward, lie down, or move your head suddenly
• radio_button_uncheckedA blocked or stuffy nose, often on one side
• radio_button_uncheckedThick nasal discharge that is yellow or green
• radio_button_uncheckedA reduced or lost sense of smell
• radio_button_uncheckedPost-nasal drip, a sore throat, or a cough that is worse at night
• radio_button_uncheckedTenderness when you press over the cheeks or forehead
• radio_button_uncheckedSometimes a fever, bad breath, or a feeling of fullness in the ears

Acute sinusitis usually follows a cold and improves within about 7 to 10 days. Symptoms that persist beyond 10 to 12 weeks are called chronic sinusitis and should be assessed by a GP, who may look for underlying causes such as allergies or nasal polyps.

The OTC Treatment Ladder for a Sinus Headache

For a true sinus headache, the most effective approach tackles both the congestion and the pain. Start with the gentlest, drug-free steps and add medicines as needed. You do not have to use every rung — many people settle a mild sinus headache with saline, steam and a simple pain reliever alone.

Step 1: Saline rinses and sprays

Rinsing the nose with salt water is one of the safest and most useful first steps. It flushes out mucus and allergens, moisturises the nasal lining, and can genuinely ease congestion without any medicine. Saline sprays (such as Fess) suit mild congestion, while a larger-volume sinus rinse (such as NeilMed) does a more thorough flush. There is no rebound effect, so you can use saline as often as you like. Our guide to saline nasal sprays and sinus rinses explains how to use each type correctly and how to keep the equipment clean.

Step 2: Steam and humidity

Warm, moist air helps loosen thick mucus so it can drain. Lean over a bowl of hot (not boiling) water with a towel over your head for a few minutes, or simply sit in a steamy bathroom after a hot shower. A warm compress held over the cheeks and forehead can also soothe the pressure. Keep well hydrated too — drinking plenty of fluid thins mucus from the inside.

Step 3: Decongestants

Decongestants shrink the swollen blood vessels in the nasal lining, opening blocked sinuses so they can drain. There are two main types, and the difference between them matters.

• radio_button_uncheckedPseudoephedrine (e.g. Sudafed) — an oral decongestant kept behind the pharmacy counter, where you will need to show ID. It is the more effective oral option and can noticeably relieve sinus pressure.
• radio_button_uncheckedPhenylephrine (PE) — the oral decongestant found on open shelves in many 'PE' branded cold and sinus products. Recent evidence has found that oral phenylephrine works no better than a placebo, so it is a poor choice for genuine congestion.
• radio_button_uncheckedMedicated nasal sprays (e.g. Otrivin, Drixine) — sprayed directly into the nose, these act fast and are very effective, but must not be used for more than a few days in a row.

Step 4: Pain and pressure relief

Simple pain relievers ease the ache while the congestion settles. Paracetamol (such as Panadol) is the gentlest option. Ibuprofen (such as Nurofen) is a good alternative because, as an anti-inflammatory, it can help with the inflammation driving the pressure. Take it at the first sign of pain rather than waiting for it to build. Be careful with combination 'sinus' or 'cold and flu' products, which often already contain paracetamol — do not top them up with more paracetamol on the side, as it is easy to exceed the safe daily dose that way.

Step 5: Steroid nasal sprays

For sinusitis that lingers, or where allergy is part of the picture, a steroid (corticosteroid) nasal spray such as Beconase or Nasonex can reduce the underlying inflammation and swelling. Unlike medicated decongestant sprays, steroid sprays are designed for longer-term use and do not cause rebound congestion, but they work gradually — it can take several days of regular use before you feel the full benefit, so they are for prevention and steady control rather than instant relief. Ask your pharmacist whether one is appropriate, and read the label for the minimum age.

When Are Antibiotics Needed for Sinusitis?

Rarely. The great majority of acute sinusitis is caused by a virus, and antibiotics do nothing against viruses. Even when a sinus infection is bacterial, most cases clear on their own without antibiotics, which is why Australian prescribing guidelines advise against routine antibiotic use for sinusitis. Taking antibiotics you do not need will not speed recovery and adds to antibiotic resistance.

Red Flags: When to See a Doctor

Most sinus headaches are uncomfortable but not dangerous. Occasionally, facial pain and headache signal something more serious. Seek prompt medical care if any of the following apply.

Book a routine GP appointment if your symptoms last beyond about 10 days without improving, keep coming back, or are not responding to OTC treatment. Recurring facial pain that never quite behaves like an infection is often migraine in disguise, and your GP can help pin down the real cause and the right treatment.

Frequently Asked Questions

How do I know if my headache is sinus or migraine?

Look at your nose and the pain quality. A true sinus headache comes with a genuinely blocked nose, thick yellow or green mucus, a reduced sense of smell, and deep facial pressure that worsens when you bend forward — usually after a cold. A migraine tends to be throbbing rather than pressing, often on one side, and comes with nausea or sensitivity to light and sound, while the nose stays clear or only runs watery fluid. Research shows most people who think they have sinus headaches actually have migraines, so if the nasal signs are missing, migraine is the more likely answer.

What is the fastest way to relieve a sinus headache?

Clear the congestion and treat the pain together. Rinse your nose with saline, breathe in steam or sit in a steamy bathroom, and take paracetamol or ibuprofen for the ache. If your nose is badly blocked, a decongestant — oral pseudoephedrine from behind the pharmacy counter, or a medicated nasal spray for no more than a few days — can open the sinuses. Staying well hydrated helps thin the mucus so it drains more easily. Ask your pharmacist which combination is right for you.

Does a decongestant help a sinus headache?

For a genuine sinus headache with real congestion, yes — a decongestant can open blocked sinuses and relieve the pressure. Oral pseudoephedrine (Sudafed) is the more effective oral option; oral phenylephrine (the 'PE' in many shelf products) has been shown to work no better than placebo. If your 'sinus headache' is actually a migraine, though, decongestants will not help, which is a strong clue that you may be treating the wrong condition.

Do I need antibiotics for a sinus infection?

Usually not. Most sinusitis is caused by a virus, and even bacterial cases often clear on their own, so Australian guidelines advise against routine antibiotics for sinusitis. Antibiotics will not help a viral infection and add to antibiotic resistance. Your GP may consider them if symptoms are severe, last beyond about 10 days without improving, or get better and then clearly worse again. See our guide on when to use antibiotics for more detail.

How long does a sinus headache last?

A sinus headache from acute sinusitis usually eases as the infection settles, typically within about 7 to 10 days. If facial pain and congestion persist beyond 10 to 12 weeks, it is classed as chronic sinusitis and should be assessed by a GP. If your 'sinus headaches' keep returning every few weeks without an obvious cold each time, they may be migraines rather than sinus infections.

Can I use a steroid nasal spray for a sinus headache?

A steroid nasal spray such as Beconase or Nasonex can help sinusitis that lingers or has an allergic component, because it reduces the underlying inflammation. Unlike medicated decongestant sprays, steroid sprays are made for longer-term use and do not cause rebound congestion — but they work gradually, so give them several days of regular use before judging the effect. Ask your pharmacist whether one suits you and check the label for the minimum age.

Why does my sinus headache get worse when I bend over?

When the sinuses are congested and full of trapped mucus, bending forward or lying down increases the pressure inside them, which intensifies the ache. This positional worsening is one of the more typical features of a true sinus headache, though it can occur with migraine too, so it is not proof on its own. Combine it with the other clues — blocked nose, discoloured mucus, reduced smell — to judge which you are dealing with.
