ALLERGIES AND SINUSITIS: WHAT’S THE DIFFERENCE?

When you suffer from allergies, or allergic rhinitis, you might experience a lot of uncomfortable symptoms. So when you feel under the weather, it can be difficult to tell if it’s just your allergy symptoms acting up or sinusitis (also known as a sinus infection). Here’s a quick look at the difference between allergies and a sinus infection.

	ALLERGIC RHINITIS	SINUSITIS
What is it?	Inflammation in the nose1	Inflammation of the sinuses (located in the forehead, cheekbones, and behind the nose)1
What causes it?	Indoor and outdoor allergens1	Sinus infection (usually caused by a virus or bacteria). But can also be caused by nasal polyps or a deviated nasal septum.2
What are the symptoms?	Sneezing, runny nose, nasal congestion, and itchy, watery eyes1	Thick yellowy mucus, sinus pressure (tenderness and swelling around the eyes, cheeks, nose and forehead), and reduces sense of smell and taste1*

Did you know?

Your skull has four pairs of sinuses, or hollow spaces, called the paranasal sinuses. Sinuses help lighten the skull, warm and humidify inhaled air, and give resonance to the voice and shape to the face. They are lined with the same kind of tissue that lines the inside of your nose.1,3
