Running water from ear holes is most often seen in diseases such as otitis externa and otitis media. Otitis externa is most often caused by habitual digging of the ear, damage to the skin of the ear canal, or water in the ear canal leading to infection, which recurs and over time leads to chronic otitis externa. It is characterized by sticky oozing or running water from the external ear canal and a pronounced itching sensation. In the acute stage, ear pain and discomfort may occur, and there is usually no hearing impairment. Treatment measures: Quit ear digging habits, avoid water in the ear canal, quit smoking and alcohol, antibiotic treatment, and timely cleaning of ear canal secretions. Middle ear infections are mostly triggered by cold, water in the ear canal, immune system decline and other factors, manifesting as ear pain, and untimely treatment may result in running water or pus in the ear canal, accompanied by hearing impairment. Treatment measures: get rid of the pathogenic factors, promptly clean the external ear canal secretions, treat the infection with antibiotics, and use antibiotic ear drops for ear drops.
