If a patient has chest pain after sleeping, it may be due to prolonged poor sleeping posture, resulting in pressure on the relevant parts of the body, which may cause such pain symptoms. It is also possible that the patient has recently overworked or exercised strenuously, resulting in strain and strain on the joints and muscles, which may cause pain. Of course, we cannot exclude the occurrence of internal chest infection, pleurisy, myocardial ischemia, myocardial infarction and other related diseases. If the pain is not relieved, electrocardiogram, chest CT, chest X-ray and other tests should be performed to clarify. If the patient is found to have internal chest infection and the diagnosis is clear on chest CT, antibiotics can be ordered for effective treatment.
