<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor,I am having severe chest pain on the left side just exactly at the same point at the back. I also feel breathlessness often feel exhausted after climbing steps...I am 26 years old my family history has heart problems.Please suggest examinations i should go through.  <response>: Welcome and thank you for asking on Chat Doctor! I have gone through your question. As you have chest pain associated with breathlessness increasingbrought on by exertion, cardiac heart cause has to be ruled out first. An ECG and 2d Echocardiography are the first and the primary investigations you have to undergo. Depending on those test a TMT treadmill test or an Angiogram may be needed. Hope to have been helpful! Wishing good health, Chat Doctor.
