In case of chest tightness and body pain, we should take the patient’s temperature first to see if the patient has fever and muscle pain caused by fever. If there is chest tightness, we should also give the patient a CT of the chest to see if the patient has chest tightness and body pain caused by infectious diseases such as pneumonia. In case of chest tightness and body pain, we should also consider whether the patient has joint pain caused by rheumatic diseases. In addition, rheumatism attacks the heart, causing rheumatic valve disease, resulting in cardiac insufficiency and chest tightness and shortness of breath. At this time, we need to check the heart ultrasound and chest X-ray to make a clear diagnosis. When the patient has chest tightness and body pain, we should also consider the possibility of infective endocarditis or pericarditis in the heart, and a heart ultrasound and blood culture can clarify the diagnosis.
