Sinusitis (Sinus Infection)

The term “sinusitis” refers to swelling of the cavities around nasal passages. When blocked and filled with fluid, mucus cannot drain from the nose. This causes germs to thrive, which often leads to an infection.


Sinus infections fall into acute and chronic categories. Symptoms are similar, but the acute version refers to an infection that clears up within four weeks. Chronic sinusitis hangs on for more than 12 weeks or can be diagnosed in a person who experiences more than three sinus infections in one year. Sinusitis sufferers report symptoms including:

  • Discolored nasal discharge (cloudy, yellow, or green)
  • Nasal congestion
  • Facial swelling and tenderness
  • Throat irritation and cough
  • Sinus headache
  • Fatigue


Sinus infections typically result from a cold virus or allergies. They sometimes develop due to a bacterial infection, nasal polyps, fungus, or a deviated septum.

Diagnosis & Treatment Options

At Harker Heights Allergy, one of our allergists will discuss symptoms with you and do an exam to determine if you have a sinus infection. In certain cases when a sinus infection has not responded to treatment, a mucus culture can provide a clearer picture of the infection source (could be bacteria or fungus). If an allergy could be at the root of your problem, a skin test may clarify which allergen is causing your nasal inflammation. Determining the root source of a sinus infection can help clarify an individual patient’s course of treatment.

Our goals in treating your sinus infections are to reduce nasal inflammation and eliminate whatever caused the initial infection. Steam inhalation and use of a nasal saline spray can help ease discomfort at home. Antibiotics, nasal decongestant sprays (used only for a short time), antihistamines, steroid nasal sprays, and antifungals are all potential treatments for sinus infections. In rare cases when other options have not worked, surgery may help eliminate the problem for good. Let us work with you to determine the best way to send your sinus infections packing.
