question: Hi, may I answer your health queries right now ?  Please type your query here...I have severe burning in the left upper side of my chest and in my left shoulder when my heart rate is elevated and/or when I am breathing cold air. I had an echocardiagram recently and it was fine.  I am a 46 year-old female. I take ju-jitsu classes and do just fine, but doing aerobic activity set my chest on fire!
