HI, I'm wondering what the pain in the left arm feels like before or during a heart attack, I might be a hypochondriac but I've been having pain in my left arm for a few days now, it is not severe and not constant, kind of feels like someone is putting pressure on a certain spot for a few seconds, then it goes away. Im worried about this because I am a smoker, i'm a woman, 38, not overweight by any means, and I drink alcohol. I also have some mild chest pains now and then, this has been going on for over a year, Ive had chest x rays, and tests for a heart attack about a year ago and everything came back fine, so I just want to know if I should be worried about this pain or write it off as nothing. Thank you.
