What is a Sinus Infection (Sinusitis)?

Sinusitis is inflammation or swelling of the tissue lining the sinuses. Your sinuses are air-filled spaces behind your forehead, cheekbones, and bridge of your nose. This inflammation blocks the sinuses, causing mucus buildup.

Several factors trigger sinusitis. Common culprits include viral, bacterial, or fungal infections. Allergies and nasal polyps also frequently contribute. Symptoms vary, but often include facial pain or pressure, headache, congestion, and a stuffy nose.

Diagnosis typically involves a physical exam and may include imaging tests like X-rays or CT scans to pinpoint the location and severity of the infection. Treatment depends on the cause and severity, ranging from over-the-counter pain relievers and nasal sprays to antibiotics (like Azithromycin, in certain cases) or antifungal medications for more severe or persistent infections.

Symptom Description
Facial pain/pressure Aching or pressure around your eyes, cheeks, or forehead.
Headache Often accompanied by facial pain.
Congestion Stuffy nose, difficulty breathing through the nose.
Thick nasal discharge Mucus can be yellow, green, or white.

Cough May be a result of postnasal drip.
Fever More common in bacterial infections.

If you suspect a sinus infection, consult your doctor for proper diagnosis and a personalized treatment plan. Early intervention improves the chances of a speedy recovery.
