right now i got this weird squeezing/pressure type feeling in my arm. its gone now but im still scared i am going to die of a heart attack. i looked it up and it said that was one of the symptoms of one and now im freaking out. my arm/shoulder has felt tired recently and my chest/back has occasionally hurt too. ive went to the er multiple times for this same issue and ive always been told that im perfectly healthy but im scared this is different im so scared i will die i desperately dont want to die im sorry if this is all over the place i cant think
