I am having chest discomfort from last 3 months, somewhat like irritation, burning sensation near left side of my chest, sometimes it causes like pinning. The pain is not severe, but it also sometimes moves to armpit and back. Consulted cardiologist, 2D echo and TMT were done on last July. One month later, did one more TMT. "Both times the reports were normal". But still sometimes there is a burning sensation around chest left side, and sometimes feels liking pinning. "Is this a thing to worry?" Do I need to consult Cardiologist once again?
