Itching in the ear, nose and throat is usually caused by allergies. Allergies are often caused by contact with or consumption of specific foods, medications and cold air after the body’s immunity and resistance have been reduced, which can cause local symptoms as well as systemic symptoms. Local symptoms include morning sneezing, runny nose, nasal congestion, decreased sense of smell, itching and pain in the throat, and difficulty breathing. Systemic symptoms may include eyelid congestion, eye itching, itching all over the body, red papules, swelling of the lower limbs, coughing and coughing up sputum. Patients first need to go to the hospital to check allergens to find out what kind of substances they are allergic to, and also need to take oral anti-allergy drugs, such as oral montelukast sodium or loratadine, and nasal cavity can be used to alleviate local symptoms with coleus or endosulfan. In general, the patient can enter the remission period in a week. After entering the remission period, the patient needs to exercise and avoid contact with allergens in order to avoid this situation.
