I have been experiencing pain in chest, breast, part between the breast- a spiking pain and since yesterday i am feeling that there is no air circulation and sometimes i have to breathe through mounth. the pain goes all the way to neck sometimes jaws, and back as well. When i do a little bit of exercise or drink water or press the area where i feel pain, i get burps. I am fine next day I had got my echo ecg done and doctor said everything is fine. results were normal. but with occasional such pains i am scared. My father, aged 62, recently passed away because of cardiac arrest and there is a history of heart problems in my family. Please advise whether i should be scared and conscious or be relaxed as i have got my tests done just a couple of months back only
