The common clinical causes of vague pain in the back of the chest are mainly the following: a. Patients with coronary heart disease can suffer from ischemia and hypoxia of the heart due to spastic contraction of the heart vessels, causing vague pain and discomfort in the back of the chest. Patients can improve the coronary CTA or cardiography examination of the heart to clarify the degree of narrowing of the heart vessels, and give symptomatic support treatment to improve the pain symptoms. Second, in patients with gallbladder stones with acute cholecystitis, the acute attack of inflammation will cause radiating pain in the right side of the chest and back. Patients can clarify the acute inflammation of gallbladder by perfecting hepatobiliary ultrasound examination, and give anti-infection, antispasmodic, analgesic and other supportive treatments. Patients with mild symptoms can usually have rapid pain relief after 3-5 days. Third, patients with acute pancreatitis can suffer from radiating pain in the chest and left back due to the large amount of pancreatic fluid exudation, and patients can have their pancreas examined by enhanced CT to clarify the severity. If necessary, surgical debridement and drainage are given, and postoperative anti-infection treatment can achieve better treatment results.
