Spring allergic rhinitis is an allergic reaction disease of the nasal mucosa that occurs in the spring, which can be manifested as paroxysmal continuous sneezing, nasal itching, and runny nose. Spring allergic rhinitis is an IgE-mediated allergic inflammatory reaction disease of the nasal mucosa that occurs in atopic individuals after exposure to specific sensitizers in spring. The process mainly involves the release of inflammatory mediators such as histamine, and the participation of immunoreactive cells and cytokines. The reason for the high incidence in spring may be related to the fluctuation of allergens, which are more frequent in spring. The main clinical manifestations are nasal itching, paroxysmal continuous sneezing, hypersecretion of the nose, a large amount of watery nasal discharge and nasal congestion. Partially due to the obvious edema of the nasal mucosa, there may be a loss of sense of smell. If there is any discomfort, it is recommended to consult a doctor in time and standardize the treatment.
