Sinusitis, often called a sinus infection, is a very common condition that can leave you feeling drained, congested, and uncomfortable. At first, the symptoms may seem like an ordinary cold but if they linger or get worse, you could be dealing with sinusitis. Knowing how to recognise the signs of a sinus infection and when to seek sinusitis treatment is key to recovering quickly and avoiding complications.
What Is Sinusitis?
Your sinuses are air-filled cavities behind your cheeks, forehead, and eyes. They produce mucus that helps keep the nose moist and filters out dust, allergens, and germs. A sinus infection develops when these passages become blocked and fill with fluid, leading to inflammation.
- Acute sinusitis: short-term, usually lasting up to four weeks
- Chronic sinusitis: lasting longer than 12 weeks, often linked to allergies, nasal polyps, or structural problems
Chronic sinusitis often requires assessment and treatment from an ENT specialist.
Common Sinus Infection Symptoms
- Persistent nasal congestion or blockage
- Facial pain or pressure
- Thick yellow or green nasal discharge
- Reduced sense of smell or taste
- Headache or fatigue
- Fever
- Bad breath (halitosis)
- Ear pressure or fullness
Nasal Congestion and Blockage
One of the most common sinusitis symptoms is a blocked nose that won’t clear up with typical cold remedies. This blockage causes pressure in the face and makes breathing difficult, often worsening at night or when lying down.
Facial Pain or Pressure:
Inflamed sinuses can cause tenderness around the cheeks, forehead, eyes, or teeth. Pain often intensifies when leaning forward or lying flat.
Thick Nasal Discharge:
Green or yellow mucus is a classic sign of infection. Postnasal drip can also irritate the throat, causing coughs and bad breath.
Reduced Sense of Smell or Taste:
Blocked nasal passages prevent odours from reaching smell receptors, dulling both smell and taste.
Headache and Fatigue:
Sinus pressure often leads to headaches, which may feel worse in the morning or when bending forward.Fatigue is also common, as your body uses extra energy to fight infection and the constant discomfort can disrupt sleep.
Fever:
A mild fever may develop with sinusitis, especially if a bacterial infection is present. A high fever combined with worsening symptoms is a signal to seek medical attention.
Bad Breath (Halitosis):
Thick mucus and postnasal drip can cause an unpleasant odour in the mouth. Even with good oral hygiene, sinus-related halitosis may persist until the infection clears.

Ear Pressure or Fullness:
Because the sinuses and ears are connected through the Eustachian tube, swelling and mucus buildup can cause ear pressure, muffled hearing, or a feeling of fullness.
When Sinusitis Becomes Chronic
If symptoms last more than 12 weeks or keep coming back, it may be chronic sinusitis. Underlying causes include allergies, nasal polyps, or a deviated septum. In these cases, consulting an ENT doctor is essential for lasting relief.
When to See a Doctor or ENT Specialist
Seek medical advice if:
- Sinus infection symptoms last longer than 10 days
- You develop severe facial pain, swelling, or a high fever
- You notice vision changes or swelling around the eyes (emergency signs)
Sinusitis Treatment Options
Self-Care and Home Remedies
For mild sinus infections, rest, hydration, steam inhalation, saline sprays, and over-the-counter painkillers can bring relief.
Medical Treatment
If bacteria are the cause, doctors may prescribe antibiotics. Steroid nasal sprays reduce swelling and inflammation. Recurrent or severe cases usually require an ENT referral for further treatment.
ENT Interventions
When structural issues or stubborn infections are the cause, procedures may be recommended:
- Endoscopic sinus surgery: restores normal drainage
- Balloon sinuplasty: a minimally invasive alternative that gently widens sinus passages
Preventing Sinus Infections
- Control allergies with medication or treatment
- Use a humidifier in dry environments
- Avoid smoking and environmental irritants
- Perform regular saline nasal rinses if prone to sinusitis
