What is Sinusitis?

Sinusitis (often called a “sinus infection”) happens when the lining of your sinuses, the small, air filled spaces around your nose, cheeks, and forehead, becomes inflamed and swollen. Instead of draining freely, mucus gets trapped, creating a perfect environment for germs to grow and for pressure and pain to build up.

Think of your sinuses like tiny rooms with very narrow doorways. When those doorways swell shut (usually after a cold or allergy flare), the rooms can’t ventilate or drain properly. That’s the core of what’s happening in sinusitis.

How sinusitis occurs

Most cases start with something that blocks or irritates the sinus openings:

  • Viral infections: The common cold or flu causes swelling and extra mucus, which can block sinus drainage.

  • Allergies: Hay fever and other allergic reactions inflame the nasal lining and increase mucus.

  • Structural issues: A deviated septum, nasal polyps, or even dental infections can physically narrow or block sinus passages.

  • Irritants: Smoke, pollution, or strong chemicals can trigger inflammation in sensitive people.

Once drainage is blocked, mucus builds up and may become thick and discoloured. Bacteria can then multiply in this stagnant mucus, turning a simple viral cold into a secondary bacterial sinus infection.

Sinusitis doesn’t just feel like a “stuffy nose.”

Typical symptoms include:

  • Blocked or stuffy nose, making it hard to breathe through your nostrils.

  • Thick, discoloured mucus from the nose.

  • Facial pain, pressure, or tenderness around the eyes, cheeks, nose, or forehead, often worse when bending forward.

  • Reduced sense of smell and taste sometimes temporarily lost.

  • Headache, toothache, or ear pain/pressure. Cough, sore throat, or bad breath from postnasal drip.

  • Tiredness or feeling generally unwell, sometimes with a fever.

How it might affect the sufferer.

Sleep disruption: Congestion and postnasal drip can make it hard to fall or stay asleep, leading to fatigue.

  • Work and concentration: Facial pressure, headaches, and tiredness can make focusing difficult and reduce productivity.

  • Social life and mood: Bad breath, constant throat clearing, or needing to pause while speaking can be embarrassing or frustrating.

  • Exercise and activities: Breathing through the nose becomes effortful; some people avoid exercise, swimming, or travel when symptoms flare.

  • Long-term impact: Chronic sinusitis, in particular, is linked to lower quality of life, ongoing fatigue, and sometimes anxiety or low mood due to persistent discomfort.

For many, it feels like living with a heavy, pressurised “band” around the face, plus the exhaustion of constantly fighting congestion.

Sinusitis is essentially your sinuses getting blocked and inflamed, most often after a cold or allergy, leading to pressure, pain, and that stubborn blocked feeling. While many cases clear on their own, persistent or severe symptoms deserve a chat with a GP, especially if they’re affecting your sleep, work, or mood.
