Babies keep scratching their ears may be caused by skin diseases, cerumen impaction, otitis media and other conditions. 1. Skin diseases: Observe whether there is eczema or seborrheic dermatitis in the baby’s external ear canal, resulting in localized skin with obvious itching, which may cause the symptom of ear scratching. 2. Cerumen impaction: Observe whether there is cerumen blockage in the baby’s ear canal. If there is too much cerumen blocking the ear canal, it can lead to the baby’s hearing loss and cause localized discomfort, and young babies who are unable to express themselves may also appear to be scratching their ears with their hands. 3. otitis media: if the baby has otitis media, there will be pain, hearing loss, uncomfortable feeling, will also scratch the ear, such as the baby repeatedly blowing his nose, can lead to otitis media. If your baby keeps scratching his ears with severe symptoms or with other symptoms, it is recommended to go to the hospital in time. Follow medical advice for treatment.
