Chest tightness, cold, don't want to eat, how to treat

Patient's question:

About a month, chest tightness, cold, don't want to eat dinner

Doctor's answer:

This could be a problem related to the patient's cardiovascular system, or it could be caused by a cold. It is recommended to conduct further examinations, at least an electrocardiogram (ECG) and a chest X-ray, to identify any issues and confirm the cause before proceeding with treatment. A blood test and a chest X-ray are necessary. If needed, a detailed ECG should be performed to determine the underlying cause.
