Sinus Symptoms and Treatment in Kolkata – Everything You Need to Know
Are you constantly dealing with a blocked nose, throbbing headaches, or facial pressure that just will not go away? You are not alone. Thousands of people across Kolkata suffer from sinusitis every year — and most of them do not even realize what is causing their discomfort.
Sinusitis is one of the most common yet most misunderstood ENT conditions in India. People often mistake it for a regular cold or seasonal allergy and keep taking painkillers for temporary relief. But without proper diagnosis and treatment from an experienced ENT specialist in Kolkata, sinus symptoms keep coming back — and getting worse every season.
In this blog, Dr. Debajyoti Das — one of Kolkata’s most trusted ENT and Head & Neck specialists — explains everything you need to know about sinus symptoms, their causes, complications, and the most effective treatment options available today.

What is Sinusitis?
The sinuses are small air-filled cavities located inside your skull — around your nose, cheeks, and forehead. These cavities are lined with a thin layer of mucus that helps filter the air you breathe.
When these cavities get inflamed or infected, the condition is called Sinusitis. The inflammation causes the sinus passages to swell and block — trapping mucus inside and creating the painful, uncomfortable symptoms that millions of people experience every day.
Sinusitis can be:
🔹 Acute Sinusitis – Lasts less than 4 weeks, usually after a cold or infection
🔹 Subacute Sinusitis – Lasts 4 to 12 weeks
🔹 Chronic Sinusitis – Lasts more than 12 weeks and keeps recurring
🔹 Recurrent Sinusitis – Several acute episodes every year
What Causes Sinusitis?
Understanding the root cause of your sinus problem is the first step towards permanent relief. The most common causes of sinusitis include:
1. Viral Infections
The most common cause. A cold or flu virus inflames the sinus lining and blocks normal drainage — leading to a secondary sinus infection.
2. Bacterial Infections
When a viral sinus infection is not treated properly, bacteria can multiply in the blocked sinuses and cause a more severe and longer-lasting infection.
3. Allergic Rhinitis
Dust, pollen, pollution, and pet dander trigger an allergic response in the nasal lining — causing chronic inflammation and repeated sinus episodes. This is extremely common in Kolkata due to high levels of dust and air pollution.
4. Deviated Nasal Septum
The nasal septum is the wall that divides your two nostrils. When it is bent or off-centre, it blocks normal airflow and sinus drainage — causing repeated infections on one side.
5. Nasal Polyps
These are small, soft, non-cancerous growths that develop inside the nasal passages. They block the sinus openings and cause chronic congestion, loss of smell, and recurring infections.
6. Fungal Infections
Less common but serious. Fungal sinusitis can be invasive and requires urgent ENT evaluation and surgical treatment.
7. Environmental Factors
Kolkata’s humid climate, heavy traffic pollution, construction dust, and seasonal weather changes make it one of the highest risk cities in India for chronic sinusitis and nasal allergies.
