I m a 24-year-old female. Slightly overweight, haven t smoked a cigarette in 2 years, but use an electronic cigarette. I have been experiencing a pain in my chest since this morning, on my left side. I ve been experiencing a sense of nausea, without actually getting sick, for about an hour. It feels as if it s a hunger pain in my stomach, but I had just eaten. Also, I feel slightly dizzy. I m worried that I might need to go to the hospital, but also feel like I m just being paranoid. What is the likelihood that this is a heart attack? I heard that they can be silent, almost unrecognizable, in women.
