Pain in the middle of the chest should first be seen by a thoracic surgeon, because some patients are suffering from diseases of the chest wall, such as costochondritis, which occurs in the anterior chest or in the thoracic rib joints and can be triggered after strenuous activities. Pain relief medication, such as oral diclofenac tablets, can be given for treatment. In patients with reflux esophagitis, pain in the posterior sternal region with heartburn and significant belching, which is aggravated after eating, and loss of appetite can also be diagnosed by gastroscopy. Usually, attention should be paid to eating small meals and not overeating. Give appropriate drugs to enhance gastric power and protect the mucosa of the gastrointestinal tract. In addition, attention should be paid to eating more vitamin-rich and multi-fiber foods, which can also improve the patient’s discomfort and prevent the occurrence of related complications.
