Below the ear is the part where the human body secretes oil. In addition, there are a lot of sebaceous glands and sweat glands in this part, which is easy to accumulate excess sebum and sweat. If personal hygiene habits are not good, this area will not be cleaned in time, which will lead to a large number of bacteria proliferation and odor.

In addition, if the individual's physique is oily, eating spicy, fried and other greasy foods will increase the secretion of sebum and sweat under the ear and increase the generation of odor. Therefore, individuals should appropriately reduce the intake of these foods and keep them clean to reduce the smell of ears.

It is best to go to the hospital and use antibiotics and other drugs according to the doctor's advice.
