I am having some chest pain and am debating as to whether I need to go to the ER. I have been having these pains on and off for the past couple of weeks, but this evening it seems to be more constant. The pain is a pressure type of pain just slightly right of the center of my chest; it is not severe, but it is noticable. It does seem to radiate to my back, especially my right shoulder blade. My blood pressure normally runs low, I have taken it 3 times in the past 1/2 hour: 112/64, 102/ 60, 103/60. I do not take any medications or have any other health issues.
