What’s wrong with a baby with a cold and earache? How old is the baby? Cold if throat inflammation or tonsillitis, due to the baby’s Eustachian tube is relatively short, that is, the pharynx and the external auditory canal of the ear, this part of the structure is relatively short and thick, so when the baby has a cold, inflammation of the throat, the inflammation will spread to the external auditory canal, causing otitis media, so the baby’s ears will hurt when he/she has a cold. In this case, it is best to take the baby to pediatrics, otolaryngology, otolaryngology, to see if there is inflammation in the external ear canal, if there is otitis media, it is necessary to clean in the ear and dispose of it to reduce inflammation. If the inflammation of the external ear canal is more serious, you need to take some anti-inflammatory drugs.
