The main causes of external ear pain in patients include the following: The first one is due to the colder and colder temperatures in winter, which can especially lead to frostbite in the patient’s auricle. If it is in summer when there may be more mosquitoes and sometimes bites from mosquitoes, the patient’s auricle will become swollen leading to pain. In the treatment should actively apply frostbite cream, or mosquito bite cream treatment. The second type is mainly due to acute auricular chondromalacia after trauma or compression of the patient’s auricle. Patients will have particularly pronounced pain, congestion and swelling of the ear. In terms of treatment, it is important to actively reduce inflammation to avoid auricular cartilage necrosis. Cefoperazone injection is commonly used clinically, and Bactrim ointment should be applied to the auricle for anti-inflammation and swelling, and the condition will definitely improve after active treatment.
