Patients with allergic rhinitis will have obvious symptoms of nasal congestion, clear runny nose, sneezing, loss of smell, headache and nasal discomfort. In this case, the nasal mucosa is obviously pale and edematous, the turbinates are congested and hypertrophied, the nasal cavity is narrowed, and there is a large amount of clear nasal secretions attached to the nasal cavity, which requires active anti-allergy treatment and avoidance of triggers. Allergic rhinitis is caused by pollen in the air and mites in the home, so you should wear a mask when you go out, and you should wash the bedding in the home to eliminate mites, and at the same time, you can use topical nasal spray medication, such as Daphnin spray, Cochlear spray or Acesopin spray, etc. The usual course of treatment is one week.
