The most common cause of itchy, runny ears is diffuse inflammation of the skin of the external ear canal due to inattention to frequent ear digging. Its inflammatory reaction can be followed by exudation of tissue fluid, which is one of the most common causes. Usually, you must pay attention to it and not make water enter the ears casually, and not to dig the ears, which can be relieved or even cured in about 1 month. If it is caused by moldiness in the external ear canal, the first thing to do is to avoid a humid and warm environment and keep the external ear canal dry. You can use topical ear drops, such as boric acid ear drops as well as fluconazole eye drops, and must treat the symptoms. Normally, you should pay attention to less diet, spicy and stimulating food as well as smoking and alcohol.
