Left chest is larger than right chest, and sometimes the left chest has some pain, the back also has.

Patient's question:

No

Doctor's answer:

Hello, after reading your description, you have left chest pain, and it also affects your back. This situation requires an electrocardiogram (ECG) to be checked.
Guidance:
Based on the symptoms, the first consideration is the possibility of heart disease. An electrocardiogram (ECG), blood pressure measurement, and potentially an echocardiogram of the heart may be needed to aid in diagnosis. Treatment should be selected based on the results.
