There may be the following reasons for pain outside the ear: First, herpes zoster infection in the auricle. Herpes infection usually occurs in the auricle and the auricular cavity, and the viral infection invades the auricular nerve, which can cause pain in the entire auricle. Secondly, there are traumatic injuries to the auricle, such as crushing injuries to the auricle during sleep, or local lacerations to the auricle caused by external forces in car accidents, etc. Wounds will certainly cause pain in the auricle, which is easy to diagnose when combined with the patient’s medical history. Thirdly, auricular suppurative chondromyelitis, which may be mostly due to the invasion of Staphylococcus aureus or Pseudomonas aeruginosa into the broken part of the auricle, resulting in localized infection of the cartilage and subchondral membrane of the auricle. Further development of the lesion may result in the expansion of the redness and swelling, black and purple surface of the auricle, local fluctuation, local abscess formation and other related diseases, which require anti-inflammatory treatment with adequate antibiotics and, if necessary, local incision and drainage and pus drainage treatment.
