Itchy nose and sneezing and runny nose often occurs in allergic rhinitis, which is prone to allergic substances such as pollen or willow allergy, dust mite allergy, animal hair, dust and so on. Allergic rhinitis is divided into seasonal and perennial. Seasonal allergic rhinitis usually flares up in specific seasons, such as spring, when symptoms of itchy nose, sneezing, and runny nose occur due to irritation from pollen and willow floss. In perennial allergic rhinitis, allergens are common such as dust mites, animal hair or dusty environments. In the treatment of allergic rhinitis, the main thing is to standardize the application of anti-allergic drugs as prescribed by the doctor, such as budesonide nasal spray, loratadine tablets, montelukast sodium tablets and so on, in order to alleviate the allergic reaction of the nasal mucosa. At the same time, it is best to cooperate with the doctor to check the allergens, and usually pay attention to stay away from allergens. If the symptoms of itchy nose and sneezing and runny nose can not be relieved, it is recommended to go to the regular hospital for desensitization treatment as soon as possible.
