Frequently Asked Questions
Can urgent care treat a sinus infection?
Yes. Our urgent care can evaluate sinus infections, provide symptom relief medications, and prescribe antibiotics when indicated.
Do sinus infections need antibiotics?
Not always. Many sinus infections start as viral colds. Antibiotics are typically prescribed when symptoms last more than 7–10 days, are severe, or worsen after initial improvement — suggesting bacterial infection.
When should I see a doctor for a sinus infection?
You should seek care if you have symptoms lasting longer than 7–10 days, high fever, severe facial pain, thick colored nasal drainage, or symptoms that worsen instead of improving.
What are the most common symptoms of sinusitis?
Facial pressure, nasal congestion, sinus headaches, yellow or green mucus, post-nasal drip, sore throat, cough, and fatigue are common indicators of sinusitis.
Can a sinus infection cause a fever?
Yes. Fever may occur, especially with bacterial sinus infections.
What causes a sinus infection?
Sinus infections can develop from viral respiratory infections, seasonal allergies, bacterial infections, environmental irritants, or structural nasal issues such as deviated septum or nasal polyps.
Can allergies lead to sinus infections?
Yes. Allergies can cause swelling and blockage in the sinuses, increasing the risk of infection.
Can sinus infections affect children?
Yes. Children may experience prolonged nasal congestion, cough (especially at night), post-nasal drip, or irritability when dealing with sinusitis.
How long do sinus infections last?
Acute sinus infections typically last up to 4 weeks. Symptoms that persist beyond 12 weeks may indicate chronic sinusitis.
When are antibiotics recommended?
Antibiotics are more likely recommended when:
• Symptoms last >10 days
• Symptoms worsen after initial improvement
• There is fever or severe facial pain
• Thick colored mucus is present
• Bacterial infection is suspected
Can sinus infections go away on their own?
Some mild or viral cases improve without antibiotics. Supportive care, nasal rinses, and hydration often help. Persistent or worsening symptoms should be evaluated.
Do you need an appointment for sinus infection treatment?
No. At our clinic, you can walk in for same-day evaluation and treatment.
