Itching inside the ears is not necessarily a fire. If the ears are itchy inside, patients are advised to go to the ENT department for an examination of the ear canal as well as the eardrum. The following diseases may cause itchy ears: 1. Repeated cerumen embolism in the ear canal. Cerumen embolism irritates the ear canal as well as the eardrum, which may lead to itchy ears, especially after the patient gets dirty water in the ear canal. 2. Eczema of the external ear canal, which may be accompanied by manifestations such as yellowish water flowing from the ear canal, can be seen during clinical examination as diffuse oozing in the ear canal with yellowish 3. Fungal infection of the external auditory canal, which may be accompanied by long-term use of antibiotic drops in the ear canal or long-term systemic application of antibiotics, resulting in a double infection in the ear canal, and fungal infection can be found by fungal smear examination of the ear canal secretions.
