If you are sneezing all the time without a cold, you should consider having allergic rhinitis. Allergic rhinitis is a metamorphic reaction that occurs when the nasal cavity is exposed to external allergens. The clinical manifestations are nasal itching, sneezing and clear watery nasal discharge, etc. When examined, the nasal mucosa is seen to be pale, edematous and more watery. If the effect is not good during treatment, it is necessary to check whether there are structural abnormalities in the nasal cavity, such as deviated nasal septum and enlarged inferior turbinates, etc., which can be solved by surgical correction and reduction of nasal mucosal sensitivity, such as nasal septum correction and inferior turbinate Ablation, etc.
