The symptoms of allergic rhinitis are numerous. Common clinical symptoms include repetitive itching of the nose, runny nose, and sneezing, which can occur consecutively several times and are directly triggered by contact with allergens. Common allergens include dust, pollen, seafood, and pets. If the allergic reaction is severe, contact with these allergens can quickly trigger the aforementioned clinical symptoms, characterized by sudden onset of nose itching, clear nasal discharge, and sneezing. In terms of treatment, oral medications and nasal sprays are primarily used. A small portion of patients might consider desensitization therapy or surgical treatment, but it is generally difficult to achieve a complete cure.
