When a patient develops a condition of pharyngitis, it may cause symptoms of rhinitis to occur. Pharyngeal and chronic inflammatory conditions are often caused by respiratory bacterial and viral infections, and may also be affected by excessive smoking, alcohol consumption, excessive consumption of spicy and irritating foods, excessive exposure to air pollution, etc. These factors may further lead to inflammatory disease conditions in the nasal mucosa. If the patient’s acute inflammatory condition of the pharynx is not treated and improved in a timely and effective manner, further aggravation of the inflammatory condition and its spread to the surrounding areas can also be an important cause of rhinitis symptoms. Patients may experience a certain degree of congestion and swelling of the nasal mucosa, resulting in nasal congestion and mucus or even purulent nasal discharge.
