question: I have had chest pressure on and off for months.  Alot of times it feels like I do not get enough air in my lungs so I take really deep breaths.   Now I have star belching alot, also.  I do suffer from anxiety, and in the past sometimes it feels like I can not get enough air in my lungs has always been associated with that for me.   I am concerned that it might be associated with my heart.
