If there is pain behind the ear, this condition generally has two clinical causes, as follows: 1. Post-auricular neuralgia attack: Post-auricular neuralgia is directly related to the patient’s prolonged staying up late, exertion and poor rest, which will result in localized pinprick-like pain behind the ear, with irregular attacks that can get better on their own. In terms of treatment, central sedation treatment is needed, and local hot compresses can also be given, while adjusting sleep and rest, the symptoms will gradually improve. 2. Pain in skin tissue caused by local compression: If the auricle is squeezed for a long time, it will lead to congestion and edema in the local skin tissue, which in turn will cause pain. When checking the local situation, it can be found that the skin temperature is higher, while swelling is more obvious. In terms of treatment, local hot compresses can be applied, while adjusting the sleeping position and avoiding repeated compression, which can heal on its own. The diagnosis can be confirmed by detailed examination of the local condition at the hospital.
