Ear cartilage pain can be caused by many reasons, such as aseptic inflammation, temporomandibular arthritis, and skin boils. When ear cartilage pain occurs, you need to go to the ENT department of the hospital as soon as possible for treatment. 1. Aseptic inflammation of ear cartilage: long-term pressure on ear cartilage may induce local aseptic inflammation, which is characterized by local redness, swelling and pain. 2. Temporomandibular arthritis: Temporomandibular arthritis can also lead to ear cartilage pain, usually more obvious after eating hard food. 3. Skin boils: If there are boils on the skin surface of the ear cartilage, they can cause ear cartilage pain before the boils mature and burst. There are many reasons for ear cartilage pain, and we suggest that you go to the ear, nose and throat clinic in time after the symptoms appear, and take standardized treatment according to the doctor’s instructions after a complete examination, so you can’t ignore the symptoms and take them lightly.
