Hi, I have a following question: Sometimes I have attacks , when my rib cage is very tense and every time I breathe in, it comes with a pain. There is also subtle pain around my heart at those moments. Although, I was not actuallly able to check my heart rate or PB, it feels like my heart is beating very fast and I can hear the rate sometimes in my head or in my hands if I try to check it. I hope it all makes sence. I went to one doctor - he could not really explain what it was and suggested not to worry. But these attacks keep coming back.
