Your allergist may examine your nose or sinus openings. If your sinus infection lasts longer than eight weeks, or if standard antibiotic treatment is not working, a sinus CT scan may help your allergist diagnose the problem. Appropriate treatment of sinus infection often improves asthma symptoms.ĭiagnosis depends on symptoms and requires an examination of the throat, nose and sinuses. Some people with a chronic nasal inflammation and irritation and/or asthma can develop a type of chronic sinusitis that is not caused by infection. Molds, dust mites and pet dander can cause symptoms year-round.Īsthma also has been linked to chronic sinus infections. Nasal and sinus passages become swollen, congested, and inflamed in an attempt to flush out offending inhaled particles that trigger allergies. ![]() It could be caused by a cold or allergies.Īllergies can play an important role in chronic (long-lasting) or seasonal rhinitis episodes. Rhinitis only involves the nasal passages. Sinus infection (sinusitis) is often confused with rhinitis, a medical term used to describe the symptoms that accompany nasal inflammation and irritation. Tenderness of the face (particularly under the eyes or at the bridge of the nose).Discolored nasal discharge (greenish in color).SymptomsĬommon symptoms of sinus infection include: People with these defects often suffer from chronic sinus infections. Nasal polyps (benign nasal growths that contain mucus).Deformity of the bony partition between the two nasal passages. ![]() Some people have bodily defects that contribute to sinus infection. The tiny hair-like “sweepers” become blocked when infections or allergies cause tiny nasal tissues to swell. This continual process is a normal body function.Ī sinus infection stops the normal flow of mucus from the sinuses to the back of the throat. From there, it slides down to the stomach. Tiny hair-like projections in the sinuses sweep the mucus (and whatever is trapped in it) towards openings that lead to the back of the throat. Normal sinuses are lined with a thin layer of mucus that traps dust, germs and other particles in the air. In rare cases, it can spread to the brain.
