Sinus Infection (Sinusitis) Treatment in Brooklyn & Queens, NYC
Understanding Sinus Infections
A sinus infection, also called sinusitis, happens when your sinus cavities — the hollow spaces behind your nose, eyes, and forehead — become inflamed or filled with mucus. It’s one of the most common reasons people visit urgent care, especially during cold, allergy, or flu season.
At AG Care, our experienced clinicians provide same-day relief for sinus infections across Brooklyn, Queens, and greater NYC. Whether it’s a mild pressure headache or a stubborn infection that won’t go away, our team is here to help you breathe easy again.
Common Symptoms of a Sinus Infection
Sinus infections can feel like a bad cold that just won’t quit. You might experience:
- Facial pain or pressure (especially around your eyes or cheeks)
- Nasal congestion or stuffiness
- Thick yellow or green nasal discharge
- Headache or tooth pain
- Fever or fatigue
- Reduced sense of smell
- Coughing or postnasal drip, especially at night
If these symptoms last more than 10 days or keep coming back, you may have chronic sinusitis — a longer-term condition that needs medical attention.
What Causes Sinusitis?
Sinus infections can be viral, bacterial, or allergic in nature. Common causes include:
- Colds and respiratory infections
- Allergies (pollen, dust, pet dander)
- Nasal polyps or a deviated septum
- You have an IUD or use spermicides
- Air pollution or cigarette smoke
- Immune system conditions
Our providers will carefully evaluate your symptoms to determine what type of infection you have — because not every sinus infection needs antibiotics.
Diagnosis & Treatment at AG Care
At AG Care, we take a thoughtful approach to diagnosing and treating sinus infections.
Your visit may include:
- A detailed exam of your nose, throat, and ears
- Possible imaging or sinus X-rays (onsite at select clinics)
- Allergy or bacterial testing, if symptoms are recurring
- Personalized treatment based on cause and severity
Treatment options include:
- Antibiotics, if a bacterial infection is confirmed
- Decongestants or nasal sprays to reduce swelling
- Antihistamines or allergy management
- Saline rinses and home care guidance

You’ll leave with a clear plan for relief and follow-up care if symptoms persist.
