The patient, Ms. Bi, had been suffering from pain and discomfort in the “heart fossa” area for more than 10 years, and had been diagnosed with coronary heart disease, gastritis, cholecystitis, and even neurosis. After detailed consultation, careful examination and improvement of relevant auxiliary examinations, the correlation between the patient’s pain in the “heart fossa” and coronary artery disease, gastritis and cholecystitis was ruled out. According to the patient’s pain site, the pain in the fossa of the heart increased after satiety, when the body was twisted and when the patient sat in a forward position, and the pressure pain was obvious at the tip of the sternal sagittal process. After one treatment, the pain in the cardiac fossa was significantly relieved, and the pain basically disappeared on the third day after the treatment, and the joy was overwhelming. It is uncommon to see the saber pain syndrome (saberitis), which is a chronic sterile inflammation of the saber due to stimulation and pulling for a long time for some reason. The anatomical characteristics of the saber are that the fourth to eighth intercostal nerves and the phrenic nerve are overlapping and staggered on both sides, and it is also a place where the organs in the thoracic and abdominal cavities are in close contact with each other. Therefore, it is easy to miss the diagnosis of the syndrome in clinical practice, and it also needs to be differentiated from heart disease, gastritis, pleurisy, etc. to avoid misdiagnosis.
