Inflammation of the ear with itching is usually a clinical manifestation of an acute otitis externa attack. Neomycin ointment can be used topically and wiped repeatedly. The cause of acute otitis externa is usually due to repeatedly pulling out the ears, damaging the skin and mucous membrane of the external ear canal and causing ear symptoms due to the invasion of bacteria and viruses, most of which are Staphylococcus aureus. On examination, swelling of the skin at the opening of the external ear canal is obvious, with localized chapping and yellowish secretions, and in severe cases, purulent secretions may also appear. Patients may experience severe pain in the ear, itching, hearing loss, tinnitus and other related symptoms. In terms of treatment, patients need symptomatic anti-inflammatory treatment oral anti-inflammatory drugs, which can be taken orally with cefixime and amoxicillin. At the same time, local rubbing with neomycin ointment twice a day will heal the ear in about a week. During the treatment period, patients should avoid pulling out the ears, avoiding water in the ears, and not eating spicy and stimulating foods.
