The following are common causes of pain in the auricle: 1. Inflammatory diseases: Inflammatory infections often occur in the auricle, which may lead to boils or infected cysts on the surface of the auricle. 2. Pseudocysts: Pseudocysts in the auricle may occur in some patients. 3. Trauma and frostbite: The auricle may also become infected secondary to trauma or frostbite, which may lead to suppurative chondromalacia, in which case the auricle may become congested, swollen and painful, and even cause fever, chills and other systemic symptoms.
