Patient: Description (onset time, main symptoms, hospital visited, etc.): Seasonal allergic rhinitis, runny nose, sneezing, which often occurs in August and September every year, and which is treated with nasal drops at Nanhui Central Hospital. Zhang Jiaxiong, Department of Otolaryngology, Shanghai Tenth People’s Hospital: First of all, it is not always seasonal allergic rhinitis that strikes in August and September every year. The prick test can distinguish whether it is allergic rhinitis or not. Many of the so-called allergic rhinitis are actually vascular rhinitis. Keep warm and avoid blowing cold air directly, and avoid direct exposure of limbs in air-conditioned rooms in summer. If it is allergic rhinitis, specific desensitization is the only treatment that can change the course of allergic rhinitis.
