I am a female,29,5'4,190 pounds,and no serious medical problems to note,i have been in a major car accident before and had to have cpr performed on me,which is why this problem is scaring me so much,i have been having chest pain which i know is my heart,all last night,and now this morning it feels like there are tiny bubbles in my heart,and this has been going on all morning,i read online that this could be due to anxiety,is that the case,or should i see a Dr??????
