what causes sinus pressure

Sinus pressure is usually caused by inflammation and swelling in the tissues lining your nasal passages and sinuses , which can trap mucus and create a feeling of pain, fullness, or pressure. Common triggers include colds, allergies, and sinus infections , and irritants like smoke or pollution can also contribute.

What’s happening

Your sinuses are normally air-filled spaces that drain mucus. When they get irritated or swollen, drainage slows down, mucus builds up, and pressure can develop around the forehead, cheeks, nose, or behind the eyes.

Common causes

• Common cold or flu.

• Allergies / hay fever.

• Sinus infection (sinusitis).

• Environmental irritants , such as cigarette smoke or pollution.

• Structural issues , like a deviated septum or nasal polyps, especially when symptoms keep coming back.

When to get checked

If sinus pressure is severe, lasts more than about 10 days, keeps returning, or comes with fever, swelling, or worsening facial pain , it’s a good idea to see a clinician.
