Allergic rhinitis is a relatively common otolaryngological disease with various clinical symptoms. The most common symptoms include itchy nose, clear nasal discharge, and sneezing. It is advisable to consider allergen testing. Common allergens in clinical settings include seafood, cats, dogs, pollen, and there may also be dust, mugwort, and pigweed. There is generally significant individual variation, and clear identification can be acquired through skin prick tests or blood tests. Once identified, it is necessary to avoid contact with the allergens in daily life as much as possible. Additionally, if the clinical symptoms are severe, it may be necessary to combine oral medications and nasal sprays for targeted treatment.
