Earache caused by a child’s cough usually does not heal on its own, so it should be treated actively by a doctor. A child’s cough with earache can be caused by bronchopneumonia, pharyngitis, bronchitis, otitis media and other diseases. Because the eustachian tube is a tube that connects the upper respiratory tract to the ear canal, inflammatory reactions in the upper respiratory tract, such as changes in mucosal congestion, edema, and exudation of inflammatory secretions, can involve the ear canal, which can cause inflammation of the ear canal and pain due to inflammatory reactions. In this case, blood tests and pathogen cultures of respiratory secretions can be performed, and if necessary, ear and nasal endoscopy can be performed to clarify the cause and then treat the symptoms and anti-pathogens. For example, you can use anti-inflammatory ear drops and anti-bacterial drugs such as penicillins, cephalosporins, macrolides, etc. Children with cough symptoms should drink more water to promote metabolism and eat a diet of foods that clear heat and lower fire, such as pears, dragon fruit, bitter melon and watermelon, to avoid further progress of inflammation.
