A boil on the external ear canal can take about 10 days to heal on its own, but only if the patient avoids picking at the ear or getting water in the ear. It takes about 10 days for the boil to break down completely, which can cause significant pain, but the pain will disappear when the boil breaks down. If an infection occurs and pus flows inside the ear, it is best to use levofloxacin ear drops to prevent the infection, plus oral antibiotics, such as roxithromycin capsules, if necessary. If the patient has no specific discomfort, it is normally possible to heal on its own. It is recommended to keep the ear clean in life to avoid the formation of boils in the external ear canal.
