So, how long does sinusitis last? Most cases clear up on their own within two to three weeks, and you can usually manage the symptoms at home without antibiotics. However, if your symptoms drag on beyond ten days, keep coming back, or start getting worse instead of better, it is time to get treatment. That dull ache behind your cheeks and forehead does not have to run its full course untreated.
In this blog, we will look at what sinusitis is, how long the different types last, what you can do at home, and when to seek help through a pharmacy.
What Is Sinusitis?
Sinusitis is inflammation of the sinuses, the small air-filled spaces behind your cheekbones and forehead, usually triggered by a viral infection such as a cold. When the lining of the sinuses swells, mucus cannot drain properly, and that buildup causes the familiar pressure and congestion.
Common sinusitis symptoms include:
- Pain, tenderness or pressure around the cheeks, eyes or forehead.
- A blocked or runny nose with green or yellow mucus.
- Reduced sense of smell.
- Headache that worsens when you bend forward.
- A high temperature, toothache or bad breath in some cases.
How Long Does Sinusitis Last?
Sinusitis usually lasts two to three weeks, but the exact timeline depends on whether it is acute or chronic. Knowing which type you have shapes how it should be treated.
Acute Sinusitis Duration
Acute sinusitis typically clears within two to three weeks, and the NHS confirms most people recover without needing antibiotics. It almost always follows a cold or flu, which is why so many people search for “sinus infection how long” during the winter months. If a cold seems to linger past the one-week mark with facial pressure and thick mucus, acute sinusitis is the likely culprit.
Chronic Sinusitis
Chronic sinusitis is diagnosed when symptoms last longer than 12 weeks despite treatment. It is less common but more disruptive, often linked to allergies, nasal polyps or dental infection, and it usually needs a GP or specialist referral rather than short-term remedies.
Acute vs Chronic Sinusitis: A Quick Comparison
The table below shows the key differences between acute and chronic sinusitis at a glance, so you can work out which one matches your symptoms.
| Feature | Acute sinusitis | Chronic sinusitis |
| Duration | Up to 4 weeks, usually 2 to 3 | More than 12 weeks |
| Common cause | Cold or flu virus | Allergies, polyps, ongoing inflammation |
| Where to get help | Pharmacy | GP or specialist |
How to Ease Sinusitis at Home
Most acute sinusitis responds well to simple self-care while your immune system does the work. The NHS recommends:
- Resting and drinking plenty of fluids.
- Taking paracetamol or ibuprofen for pain and fever.
- Holding a warm flannel over your face to ease pressure.
- Rinsing your nose with a saline solution.
- Avoiding smoky environments and allergy triggers.
When Should You Get Treatment for Sinusitis?
Get treatment if your symptoms show no improvement after ten days, if you notice your sinusitis getting worse after initially easing, or if you develop a high fever. NICE guidance notes that symptoms lasting beyond ten days may indicate a bacterial infection, which can benefit from a steroid nasal spray, drops, or, in some cases, antibiotics. Seek urgent help if you have severe swelling around the eyes, changes to your vision or a very severe headache, as these are rare but serious complications.

Frequently Asked Questions (FAQ’s)
How long does sinusitis last without treatment?
Acute sinusitis usually clears within two to three weeks without treatment, as most cases are viral. If symptoms persist beyond ten days without improving, it is worth seeking advice from a pharmacist.
How do I know if my sinusitis is bacterial?
Bacterial sinusitis is more likely if symptoms last longer than ten days, worsen after starting to improve, or come with a high fever and severe facial pain. A pharmacist or GP can assess this and recommend treatment.
Can a pharmacist treat sinusitis in the UK?
Yes. Under the NHS Pharmacy First scheme, pharmacists can assess sinusitis in anyone aged 12 and over with symptoms lasting more than ten days and supply treatment, including antibiotics where appropriate.
How can you ease sinus pressure fast?
A warm compress over the face, saline nasal rinses, steam inhalation and staying well hydrated offer the quickest relief. Paracetamol or ibuprofen will ease the pain while the inflammation settles.
When does sinusitis become chronic?
Sinusitis is classed as chronic when symptoms continue for more than 12 weeks despite treatment. Chronic sinusitis usually needs a GP assessment to identify underlying causes such as allergies or nasal polyps.
Is sinusitis contagious?
Sinusitis itself is not contagious, but the cold and flu viruses that commonly trigger it are. Good hand hygiene and covering coughs and sneezes reduce the risk of passing those viruses on.
