The most common clinical causes of sternocarpal pain are as follows: a. If the local pain is caused by trauma, most of them are caused by foreign body impact or injury by other people, resulting in local subcutaneous bleeding or bone contusion, which leads to pain, mainly manifested by local pressure pain, and combined with percussion pain, which can be induced by deep breathing. If there is no trauma, the sternocarpal pain is due to local fascial inflammation or cartilage inflammation, which mainly manifests as local stabbing pain or radiating pain, with obvious pressure pain, but no obvious percussion pain. Usually medication is needed, generally based on non-steroidal anti-inflammatory and analgesic drugs, such as the commonly used clinical Cilabao capsules, and if the pain is fixed and there is no trauma, local drug closure treatment can also be carried out.
