hi, I have been having chest tightness and pain between my rib cage. The pain seems to go through to my back and hurts worse when I breath in. It feels like something is sitting there at the bottom between my rib cage. However, tonight the feeling move dto my upper left back near my shoulder blade and hurts when I breath in. It doesn't really hurt when I don't breath in but it just feels like something is there. Is this something I should be worried about? It feels very tight and now I am getting anxious. I should also mention I have had an abnormal ekg which showed I have right bundle branch block which I was told is normal for me. I guess my heart beats differently than most for example instead of abcd mine beats acdb. I also had an echo which showed trace mitral valve regurgitation and trace tricuspid valve regurgitation, other wise everything else was fine. Can anyone help? Thank you oh so much!!! mtiffany
