Is it allergies or a sinus infection? Knowing how to tell the difference is essential for getting the right treatment—especially in a place like New York City where both conditions are common. Allergies and sinus infections (sinusitis) share similar symptoms such as nasal congestion, pressure, and headaches, but they have different causes and require different treatments.
This blog explains how to distinguish between the two and what to do if your symptoms persist or worsen.

While both conditions inflame the nasal passages, allergies are immune-based, while sinus infections are typically infectious.
Although the symptoms overlap, there are some telltale signs that can help you tell allergies from sinus infections:
If symptoms worsen over time or persist beyond 10 days with facial pressure and fever, it’s likely an infection.
A board-certified allergist will conduct a thorough medical history and may recommend:
Correct diagnosis is essential to avoid using antibiotics when they’re unnecessary or ineffective.
Patients who suffer from recurring sinus infections may benefit from further evaluation to rule out allergies or structural issues.
In some cases, untreated allergies can set the stage for sinus infections. Constant inflammation and mucus buildup create the perfect breeding ground for bacteria. That’s why managing allergies can help prevent sinus problems altogether. Patients who treat their allergies often experience fewer sinus infections and a better quality of life.

Best allergy treatments for kids focus on safety, effectiveness, and long-term quality of life. In a city as active and allergen-rich as New York, having a solid pediatric allergy care plan is especially important — not just to relieve symptoms, but to allow children to play, learn, and grow without constant discomfort. Below is a parent-friendly guide to the most effective approaches for treating childhood allergies.

Children are not small adults — their immune systems, growth patterns, and exposure risks are different. A pediatric allergist can tailor care specifically to a child’s age, development, and unique triggers. Without specialized care, allergy symptoms can interfere with sleep, school performance, play, and overall well-being.
For moderate to severe allergies that don’t respond to basic management, immunotherapy may be appropriate:
A child should be evaluated by a specialist if:
An allergist can offer a full diagnostic workup including skin testing, blood work, and lung function testing if necessary.
Pediatric allergy care isn’t just about treating symptoms — it’s about improving the child’s ability to thrive. This includes helping them:
Parents, caregivers, and teachers all play a role in creating an allergy-friendly environment — especially in shared spaces like schools, camps, and daycare centers.
If your child is showing signs of allergies, early evaluation can make a big difference in their health and happiness. Schedule a consultation today for pediatric allergy testing and treatment tailored to your family’s needs.
