If the ear canal is blocked due to pus flowing from the ear, there will often be more or thicker purulent secretions in the ear canal. You can go to the hospital and use professional tools such as a suction device to clean it up, and if necessary, use hydrogen peroxide in combination to clean it up, which can help clean up the thick secretions better and more thoroughly. Anti-infective medications, such as penicillin or cephalosporin antibiotics, and antibiotic ear drops such as oxyfloxacin ear drops, are often used to provide direct local anti-inflammatory and antiseptic effects. In conclusion, if the ear canal is blocked due to pus flowing from the ear, you need to pay attention to cleaning the pus secretions in the ear canal as thoroughly as possible and keeping the ear canal open for drainage.
