Burning ears may be caused by temperature factors, sympathetic nerve excitation, ear trauma, and purulent perichondritis of the auricle. 1. Temperature factor: If there is a change in temperature, such as exposure to cold air or sudden entry into a hotter environment, it will easily lead to ear burning. 2. Sympathetic nerve excitation: If you are emotionally excited, drink too much alcohol, or exercise strenuously, you are prone to accelerated blood circulation, which leads to increased blood flow in the ear blood vessels and causes the symptoms of burning ears. 3. Ear trauma: when there is auricular contusion, auricular laceration, etc., it will lead to local skin and tissue stimulation, causing local skin vasodilatation, accelerated blood circulation, resulting in ear burning. 4. Auricular suppurative chondritis: it is due to bacterial infection of auricular cartilage and cartilage membrane, the formation of suppurative inflammation, the emergence of the auricle of the burning, redness, swelling, pain and other symptoms. Patients with burning ears should go to the hospital in time, clarify the cause of the disease and follow the doctor’s instructions for treatment.
