If you feel itchy after getting water in your ear, you should consider the possibility of eczema in the external ear canal. In addition to taking a medical history, it is important to ask whether there is a purulent discharge from the ear, or whether there is intermittent tinnitus or even hearing loss as an accompanying symptom. If the patient only feels itching and discomfort in the ear, without any other complaints, the signs will show eczema-like changes in the skin of the external auditory canal through electron microscopy or rigid otoscopy, a small amount of cerumen exudation, and an intact eardrum without obvious congestion, redness, or perforation. In this case, it is basically clear that it is eczema of the external auditory canal. The eczema can be treated by applying ointment to the external ear canal, such as Pirexone ointment, and instructing the patient to keep the ear dry, avoid getting water in the ear, and avoid repeatedly pulling out the ear with sharp instruments. Oral anti-allergy medications can also be taken to promote the relief of itching symptoms as soon as possible.
