I'm a 21 year old who constantly thinks in going to have a heart attack. I've been feeling this way for the past 3 months. (After my first anxiety attack) Its symptom after symptom. My left arm hurts, sometimes the right. I get lightheaded, I feel palpitations and just recently my chest started to hurt and felt like pressure. I've got 2 ekgs done and they came back normal, as well as blood tests and X-rays. All normal. They said the pressure on my chest was costochonditritis. But why do I keep feeling like something is really wrong?
