Sinus Infection

• Sinus infections can be acute, subacute, or chronic
• Often develop after a cold or upper respiratory infection
• Can be caused by viruses, bacteria, or allergies
• Most acute cases improve within 10–14 days
• Chronic sinusitis may require specialty care

Symptoms of a sinus infection may include:

• Facial pain or pressure around the eyes, nose, or forehead
• Nasal congestion or blockage
• Thick nasal discharge (yellow or green)
• Headache
• Reduced sense of smell or taste
• Metallic taste in mouth
• Postnasal drip
• Fever or fatigue

Sinus infections occur when inflammation or blockage prevents normal sinus drainage. Common causes include:

• Viral upper respiratory infections
• Bacterial infections
• Allergies causing nasal swelling
• Nasal polyps or structural issues
• Deviated septum
• Environmental irritants

You may be at higher risk for sinus infections if you:

• Have frequent colds or allergies
• Smoke or are exposed to secondhand smoke
• Have asthma
• Have nasal polyps or a deviated septum
• Have a weakened immune system

Treatment depends on the cause and duration of symptoms and may include:

• Rest and increased fluid intake
• Nasal saline sprays or rinses
• Decongestants or antihistamines
• Pain relievers or fever reducers
• Antibiotics for certain bacterial infections
• Steroid nasal sprays or oral medications
• Referral to ENT for chronic or recurrent cases

See a doctor if symptoms last longer than 10 days, worsen after initial improvement, recur frequently, or are accompanied by high fever, vision changes, or severe facial swelling.
