Is it Allergies or a Sinus Infection?

Are you stuffed up and feeling sick? Are you wondering if it is your allergies flaring up or if you have a sinus infection that needs to be treated? The answer is: it could be both.

Allergies cause nasal passages to become inflamed, and sinus infections are a common complication of allergies. It can be difficult to tell the difference between these two conditions, although there are some clues that can help.

Causes, Symptoms, and Treatments (Allergies & Sinus Infections)


  • Allergies are caused by environmental factors, such as food, plants, pets, and chemicals.
  • Sinus infections are caused by a bacterial or viral infection in the nasal cavity.

Sinus infections are generally treated with antibiotics if it is a bacterial infection. Viral sinus infections are treated with over-the-counter antihistamines and decongestants. 

  • A sinus infection should be diagnosed by a medical professional who will develop a treatment plan.
