If there is a large amount of pus in the ear canal due to prolonged immersion, it is necessary to use hydrogen peroxide solution to clean the pus. At the same time, topical antibiotic ear drops are applied, and systemic oral antibiotics are given if necessary. If there is a large number of herpes in the ear canal, due to allergic factors, you need to use topical glycerite to reduce oozing, and appropriate use of anti-allergic drugs. If there is a dark brown solid presence in the external auditory canal, it may be a fungal infection, which needs to be combined with the bacterial culture of the secretion to further confirm the diagnosis, you can use sodium bicarbonate to clean the external auditory canal, use topical antifungal medication, and pay attention to keeping the local area clean and dry.
