Sinus Problems

Sinuses are air-filled spaces located behind the cheeks, between the eyes, and above the forehead. They help moisturize and warm the air you breathe, while also influencing the tone of your voice.

When the drainage passages between the sinuses and your nasal cavity become blocked often after a cold or viral infection, this pressure builds up, leading to pain, congestion, and discomfort. In Singapore’s humid climate, sinus conditions are common and often more persistent.

Symptoms, Causes & Triggers

Common signs of sinus issues include:

Nasal blockage or obstruction
Yellow or green nasal discharge
Pain or pressure behind the cheeks, forehead, or around the eyes
Toothache, reduced sense of smell, or bad breath
Children may also show irritability or breathe through the mouth

Acute sinusitis typically clears within 7–10 days, while symptoms lasting beyond 3 months may indicate chronic sinusitis.

Sinus problems can be triggered by several factors, including:

Viral upper respiratory infections like colds or flu (most common cause)
Nasal polyps and allergic rhinitis
Smoking, weakened immune defence, or exposure to dust, chemicals, or fumes

Treatment Options

1. Self-Care

For mild, post-cold symptoms

2. Medical Treatment

Antibiotics if a bacterial infection is suspected
Nasal douche with saline or sodium bicarbonate solution to clear mucus and promote drainage
Nasal steroid sprays to reduce inflammation and swelling

3. Surgical Treatment

For recurrent or chronic cases

After assessments, possibly including imaging or endoscopy, surgery such as Functional Endoscopic Sinus Surgery (FESS) may be considered to open up sinus drainage pathways
Performed under general anesthesia; recovery usually includes 1–2 weeks’ medical leave, follow-up cleaning, and nasal douching
Full recovery typically within a month

Frequently Asked Questions

Is this just allergy or a sinus infection?

Allergies and sinusitis share symptoms, but sinusitis often follows a viral illness and includes facial pressure or discolored mucus.

How long should sinus symptoms last?

Acute sinusitis typically resolves in 7–10 days; symptoms lasting beyond 3 months may indicate chronic sinusitis.

Can sinusitis go away on its own?

Mild viral cases often improve without treatment, but persistent or severe cases may require medical intervention.

Are antibiotics always needed?

Not always—antibiotics are used when a bacterial infection is likely; mild viral sinusitis may resolve with supportive care.

Is surgery a last resort?

Yes—surgery is considered after medical treatments fail, especially for structural issues or chronic sinusitis.
