There are two main conditions that can be considered when a patient has pain in the outer contour of the ear: the first is caused by the patient squeezing the auricle for a long time while sleeping. In terms of treatment, patients can rub the auricle appropriately to promote blood circulation and the pain should be significantly reduced. The second type is mainly due to bacterial infection of the auricle and acute auricular chondromyelitis, which is particularly painful and sometimes swollen, and even accompanied by fever. In terms of treatment, patients can use ice packs to apply cold compresses to the auricle, while using compound polymyxin B or Bactrim ointment on the surface of the auricle, which can effectively play a role in anti-inflammatory and swelling, and if necessary, add levofloxacin capsules to be taken orally for 3 days, and the condition will improve significantly in about a week of active treatment.
