Sinusitis is one of the most frequently diagnosed conditions in UK general practice, affecting around 1 in 8 adults every single year. It occurs when the hollow cavities behind your cheekbones, forehead, and nose become inflamed and blocked — causing a build-up of mucus, pressure, and pain that can make even the simplest daily tasks feel exhausting.
Many people mistake sinusitis for a stubborn cold that refuses to clear. The key difference is that sinusitis causes a distinctive facial pain and pressure that a common cold simply does not. Left untreated, sinusitis can linger for weeks or develop into a more serious bacterial infection that requires prescription medication to resolve.
Sinusitis symptoms can range from mildly irritating to completely debilitating, depending on the severity and type. The most common symptoms our GPs see include:
Understanding which type of sinusitis you have is essential for getting the right treatment:
Acute Sinusitis: The most common type, usually triggered by a cold or upper respiratory infection. Symptoms develop quickly and typically last between 2 and 4 weeks. Most cases are viral and will resolve on their own, though bacterial cases require antibiotic treatment.
Subacute Sinusitis: A middle-ground form where symptoms persist for 4 to 12 weeks despite initial treatment. Often requires a more targeted course of antibiotics and further investigation.
Chronic Sinusitis When sinusitis symptoms last for more than 12 weeks, it is classified as chronic. This may be linked to nasal polyps, allergies, or a structural issue within the nasal passage and often requires specialist ENT review.
Recurrent Sinusitis: Four or more separate sinusitis episodes within a single year. Recurrent cases should always be investigated to identify and address the underlying cause.

Our doctors will take a full assessment of your symptoms and medical history before recommending the most appropriate treatment plan for your individual case:
✓ Prescribe a targeted course of antibiotics for confirmed bacterial sinusitis
✓ Recommend nasal corticosteroid sprays to reduce inflammation and swelling
✓ Advise on saline nasal irrigation to flush out blocked mucus
✓ Recommend safe over-the-counter decongestants for short-term symptom relief
✓ Investigate and address any underlying allergies contributing to your sinusitis
✓ Refer you to an ENT specialist if your sinusitis is chronic or recurring
