Sinusitis is inflammation of the sinuses, the air-filled spaces behind your forehead, cheeks, and nose. When this inflammation lasts twelve weeks or longer despite treatment, it is called chronic sinusitis. It is one of the most common reasons people visit an ENT specialist, and while it is rarely dangerous, it can significantly affect quality of life.

What causes chronic sinusitis?

Chronic sinusitis develops when the sinuses cannot drain properly and mucus builds up. Common contributors include nasal polyps, a deviated septum, ongoing allergies, repeated infections, and conditions such as asthma. In some cases a fungal infection or a weakened immune system plays a role. Often, more than one factor is involved.

Common symptoms

The hallmark signs include a blocked or stuffy nose, thick nasal discharge, facial pain or pressure around the eyes and cheeks, and a reduced sense of smell. Many people also notice post-nasal drip, a persistent cough, bad breath, fatigue, and headaches. Unlike a common cold, these symptoms linger for weeks or months.

How is it treated?

Treatment usually begins with conservative measures. Saline nasal rinses help wash away mucus and irritants, while steroid nasal sprays reduce inflammation. Your doctor may prescribe antibiotics if a bacterial infection is present, and managing underlying allergies is often key. Staying hydrated and using steam inhalation can also bring relief.

When these steps are not enough, an ENT specialist may recommend a CT scan and endoscopy to look inside the sinuses. For structural problems or stubborn cases, minimally invasive surgery such as functional endoscopic sinus surgery (FESS) can open blocked drainage pathways and provide lasting improvement.

When should you see a doctor?

Book an appointment if your symptoms last more than ten days, keep returning, or do not improve with over-the-counter remedies. Seek urgent care if you develop a high fever, swelling or redness around the eyes, vision changes, or a severe headache, as these can signal a more serious complication.

The good news is that chronic sinusitis is highly manageable. With the right diagnosis and a tailored treatment plan, most people find significant and lasting relief.
