Patients with itchy ears in the middle of the night, sometimes unable to sleep because of the itchy sensation, and sometimes yellow water may seep out of the ear canal, are generally considered to have eczema of the external ear canal. Eczema is mainly related to the patient’s body type and the fact that the ear canal is often in a humid environment. The itchiness is particularly pronounced and sometimes affects normal work or study. In terms of treatment, first of all, the patient must keep the external ear canal clean, if there are secretions in the canal, it is best to go to the hospital to line hydrogen peroxide clean out, and after that apply foam compound ketoconazole cream in the ear canal, which can effectively play a role in stopping itching. Patients should also exercise more to enhance their resistance, and can take oral pidomod oral solution or transfer factor to enhance their resistance. After active treatment, the patient’s condition should improve, but if the itchiness is still particularly pronounced, you need to go to the hospital for detailed examination.
