Fungal ear infections require ear canal cleaning and topical use of antifungal medications (e.g. salicylic acid ear drops) under the guidance of a doctor. 1. Ear canal cleaning:First of all, the ear canal should be cleaned so that there is no foreign matter in the ear canal, including the use of saline rinsing, instrument cleaning and other methods. 2. Anti-fungal medication:When the ear canal is infected with fungus, you can use anti-fungal medication (such as Trimethoprim Econazole, Itraconazole Ointment and Salicylic Acid Ear Drops) under the guidance of your doctor. In case of fungal infections in the ear canal, the main signs are itching, pain in the ear, and secretion of pus-like fluid in the ear canal. When these situations occur, you need to immediately seek further medical examination, and after a clear diagnosis, treatment by a professional doctor. Avoid aggravation of the condition and delay in treatment.
