I have been having chest pains for 6 mos. now. They are not sharp pains-more just annoying pains. I am 21 years old, never smoked or did any type of drug. I am not overweight but I have gained and lost weight over the past year.(20 pounds) I went to the doc and got a x ray done, a ekg, and a blood test and everything showed healthy. SShe even said everything was "very healthy". I am thinking that it may just be stress but why does it go away then on other days it is an all day thing? My questions is-if everything showed up fine on the x ray, blood test, and ekg am I ok or could something else be going on that doesnt show up in those tests? I am only 21 and I am worrying myself crazy wondering what is going on in my chest. Could is possibley be my breast sinceis it right on top of it. It hurts more often on the right side right above my breast. thanks!
