Brief Answer:
Further Clinical and Cardiac evaluation necessary...

Detailed Answer:
Hello,

Well, there can be several reasons behind such pain, please provide the following details:

Your age, please...

-How bad is the pain (on a scale of 1-10, 10 being the worst)? Any heaviness over the chest, any excessive sweating?

-How is the pain? Is it constant or coming and going?

-Could you specify where/which part of the left side of the chest do you feel the pain?

-Is the pain remaining constant in one area or spreading to somewhere else as well?

-Is there any pain during breathing? Or any pain during any specific activities e.g. climbing stairs, walking faster/during daily household chores?

-Any recent history of cough/cold/flu? Any history of smoking/drinking, any cardiac history in the family?

You should be investigated and examined by a Physician as management can be done based on the findings thereafter...

Take Care
Kind Regards
