Itchy throat, itchy nose and itchy ears are clinically more common diseases, such as allergic rhinitis, associated allergic pharyngitis and ear canal eczema. In this case, it may be related to the patient’s allergic constitution. It may be caused by eating allergy-prone food or contacting some allergic substances in the ears, nose and throat, which may trigger the manifestation of allergy in the throat, nose and ears. If you can find the allergen and avoid it, the symptoms of allergy will be significantly reduced. Allergic rhinitis can be improved by spraying the nose with nasal spray hormone to improve the allergy symptoms. Oral antihistamine can also be taken to relieve the itchy nose, as well as the itchy throat and itchy ears. For patients with itchy throat and itchy ears, most of them appear due to the accompanying nose, which is usually not too heavy, and the skin of the ear canal can be seen to be slightly congested when examined. It does not exclude individual patients, who have acute eczema in the ear canal, yellow water from the ears and other manifestations, and patients with itchy throat, who may also have a dry cough and other related manifestations.
