What symptom is the pain in the lower left corner of sternum?

The main manifestations are sternal pain, which is aggravated when standing and bending, and can't get up when lying flat. Although this situation is similar to reflux esophagitis, chest pain caused by chest wall and sternum itself should be ruled out first, such as. 1, chest wall muscle spasm: the most common, often caused by long-term posture, bending over, helping the case, strenuous exercise or persistent cough, local cold, etc. , causing chest wall muscle fatigue spasm, causing chest pain. Mainly manifested as local tenderness, chest pain aggravated during chest activities, such as deep breathing, turning over, chest expansion and other pain, indicating that the lesions are mostly in the chest wall. 2. Hematological diseases can also cause sternal tenderness, which should be paid attention to. The typical symptoms of reflux esophagitis are: 1, chest pain with heartburn and acid reflux, which often occurs after meals 1 hour. When lying in bed, sleeping in bed at night, bending over or increasing abdominal pressure, acidic liquid or food may flow back into the pharynx or mouth; 2. Most patients have a burning sensation or pain behind the sternum or at the heart socket, which can be induced in semi-supine position, body flexion or strenuous exercise, and disappear after taking antacid. Food that is overheated and sour will get worse. According to the above situation, you can make the following self-diagnosis: 1. Press the sternum to see if there is any local tenderness point. If there is tenderness, the pain is mostly in the chest wall. 2, when the chest pain is sour, such as Xing Shule or Wei Shuping, see if there is any relief. 3, reflux esophagitis chest pain is related to eating. Examination: 1, chest film, blood routine; 2, suspected reflux esophagitis can be examined by gastroscope or barium meal first, and gastroscope is better than barium meal. Your left sternum hurts, and your esophagus is normal after barium meal. You can rule out reflux esophagitis. But duodenitis is found, which is generally not related to chest pain. Duodenal enteritis can be asymptomatic, but also has epigastric discomfort, fullness, belching, acid reflux and so on. Those without obvious symptoms are often found during physical examination. Therefore, it is best to have a chest X-ray examination, besides the lung condition, check a blood routine. If there is nothing unusual, it is mostly caused by pectoral muscle spasm. Chest muscle spasm is a soft tissue disease, not a bone disease, so the chest film can't be found, but if the sternum or ribs are abnormal, the chest film is helpful. Chest pain can be examined in thoracic surgery.
