A sore throat and foul breath may signal that a person has chronic sinusitis, according to Mayo Clinic. Causes include certain allergens; nasal polyps, which are growths on sinuses or nasal passages; certain diseases, such as human immunodeficiency virus and cystic fibrosis; and deviated nasal septum. Respiratory tract infections may cause inflammation and thickening of sinus membranes and interfere with drainage of mucus, causing the problem as well.
A medical examination, MRI, CT can or rhinoscopy can help to diagnose the condition, notes Mayo Clinic. Tissue cultures may provide a diagnosis if treatments fail to reverse the problem.
Treatments, which help treat underlying conditions, clear nasal passages and reduce other symptoms, include applying or taking corticosteroids, nonprescription pain relievers, decongestants and saline sinus rinses. Warm compresses and rest may help as well. If left untreated, chronic sinusitis may cause serious complications such as meningitis, aneurysms, asthma, blurry vision and blindness. Using a humidifier, washing hands often, avoiding people with colds and treating allergies may help prevent the disease.Learn more about Conditions & Diseases
