What Are Sinus Infections and Seasonal Allergies?

A sinus infection, also referred to as sinusitis, is an inflammation of the tissues that line the sinuses. The sinuses are air-filled spaces that are connected to the nasal passages. Sinus infections can be caused by viruses, bacteria, or even fungi. The infection is typically acute, lasting for around a week. In more rare instances, sinusitis can be chronic and last more than 12 weeks.

Allergies, on the other hand, are an immune system response to a foreign substance, like pollen, mold, or pet dander. These substances are known as allergens and can trigger a range of symptoms, including nasal congestion, sneezing and itchy eyes.

Symptoms of Sinus Infection vs. Allergies

The symptoms of sinus infections can be similar to those of allergies, but they tend to be more severe and can last longer without the proper treatment. If you experience any symptoms indicative of sinus infection, it’s important to seek medical attention as soon as possible. If left untreated, sinusitis can lead to potentially serious complications.

Some common sinus infection symptoms include:

  • Facial pain and pressure
  • Nasal congestion
  • Loss of smell or taste
  • Cough
  • Fever
  • Fatigue

In comparison, allergy symptoms tend to be more mild than sinus infection. They vary from person to person depending on the allergen that’s triggering a reaction. The symptoms may occur seasonally, or occur through direct exposure to the allergen.


Some common allergy symptoms include:

  • Sneezing
  • Runny nose
  • Nasal congestion
  • Itchy eyes, nose, throat
  • Watery eyes

How to Know If You Have a Sinus Infection or Allergies

If you’re experiencing symptoms that you believe may be related to allergies or sinusitis, there are a few ways to tell the difference. To start, examine your nasal congestion (if present). If you have nasal discharge, look at the color to determine which condition you’re potentially dealing with. Sinus infections generally reveal thick, yellow or greenish discharge while allergies may present thin and clear discharge. Besides nasal congestion, make sure to consider the timing of your symptoms. If they become noticeable during certain seasons, like the beginning of spring, you might be dealing with allergies. Sinus infections can occur at any time of the year.

Furthermore, evaluate the severity of your symptoms. Sinusitis tends to be more severe and focused in the face– facial pressure and pain. Allergy symptoms are usually milder and focused in the eyes, nose, and throat. If you’re experiencing symptoms that are significantly affecting your daily routine, or persisting overtime, be sure to seek professional care.
