Itchy throat and constant urge to cough are symptoms of allergic pharyngitis. Allergic pharyngitis is caused by contact with allergens, such as willow wool, pollen, dust and mites, which cause an allergic reaction in the throat, causing an itchy feeling in the throat and irritating the mucous membrane with constant urge to cough. In this case, it is important to wear a mask when you go out to reduce the chance of contact with allergens. When you go home, you can gargle and drink more water to remove allergens and reduce allergic reactions. People with severe allergies should try to stay at home in the spring and avoid contact with pollen and willow. Usually pay attention to rest, don’t stay up late, and exercise properly to improve the immunity of the body, which can reduce the allergic reaction. You can use budesonide nebulized inhalation twice a day for 1 week. You can take oral anti-allergy drugs such as loratadine to effectively relieve the symptoms, or you can combine it with anti-inflammatory and detoxifying Chinese medicine such as Liushenwan to reduce the inflammation of the pharyngeal mucosa and promote the recovery of symptoms.
