Suggestion: Sinusitis itself is caused by inflammation of other parts of the nose, and the secreted viscous substance blocks the ostium of the sinus, which leads to a large number of bacteria in the sinus, thus causing inflammation of the sinus. Wash your nose with warm salt water in the morning and evening. Wash the things that block the sinus ostium, the sinus ostium is unobstructed, the secretions in the sinus can be discharged in time, and the bacteria are reduced. Sinusitis naturally disappears slowly. Moreover, long-term cleaning of nasal cavity can also make healthy newborn cells replace diseased cells in other inflamed areas, thus achieving the purpose of treating sinusitis.
