What Is a Sinus Infection?

Sinusitis is inflammation of the tissue lining the sinuses, often caused or complicated by allergies, structural abnormalities, immune dysfunction, or infection. Acute sinusitis lasts up to four weeks, while chronic sinusitis persists for 12 weeks or more despite treatment. Allergic rhinitis is a major risk factor for chronic sinusitis because ongoing nasal inflammation impairs sinus drainage and creates an environment prone to infection.

Common Signs & Symptoms

Facial pain, pressure, or fullness, particularly around the forehead, cheeks, or eyes
Nasal congestion and difficulty breathing through the nose
Thick yellow or green nasal discharge
Postnasal drip causing a sore throat or persistent cough
Reduced or absent sense of smell
Fatigue, headache, and ear pressure

How We Diagnose

Our evaluation for sinusitis includes a detailed symptom history and physical examination, assessment of allergic triggers through skin testing or blood testing, evaluation for underlying immune deficiencies that may predispose patients to recurrent bacterial infections, and coordination with ENT specialists when anatomical factors such as nasal polyps or a deviated septum require further evaluation.

Treatment Options at South Bay Allergy

Depending on the cause and severity, treatment may include targeted antibiotics for acute bacterial episodes, intranasal corticosteroids to reduce mucosal inflammation, saline nasal irrigation to improve mucus clearance, allergen immunotherapy to address the allergic component contributing to chronic inflammation, and evaluation and management of immune deficiencies when recurrent infections suggest an underlying immune disorder.
