question: Hi, may I answer your health queries right now ?  Please type your query here... hi, I am 37 years old and for two days I am feeling some heaviness in my upper left chest that is not going away.  I am light headed a little bit in the mornings but then it is going away. I have never had any heart problems or my family does not have history of heart disease so I am not sure about it.  Would you advise me if it is something serious?
