Otitis externa can heal on its own, depending on the severity of the disease and the patient’s own resistance. However, it is not recommended to wait for the disease to heal on its own, as this may delay the diagnosis and treatment of the disease. When the disease is mild and the patient’s own resistance is strong, otitis externa may heal on its own. Mild otitis externa only manifests itself in the form of mild pain in the ear canal. If you actively clean the external ear canal, stop digging your ears, and keep the area dry and drained, the inflammation can usually subside naturally after a few days. If the condition is more serious, the ear canal is swollen and burning, accompanied by purulent discharge, hearing loss, the possibility of self-healing is smaller. It is recommended that broad-spectrum antibiotics such as cephalosporins be used as early as possible to fight infection, and aminoglycoside antibiotics are prohibited. If you suspect that you are suffering from otitis externa, you should go to the hospital in time, and improve the relevant treatment and medication under the guidance of the doctor.
