Lately I have been very paranoid I am having, or going to have, a heart attack. my symptoms are: lightheadedness, dry cough, an itchy feel inside my chest, clammy hands and feet. None of these have occurred at the same time however. The lightheadedness only happened once, as well as the clammy hands and feet. I do not have any pressure or pain in my chest. These feelings send me into a panic attack when they happen and it is hard to determine if it is anxiety or something more serious. As far as medications, I take 3mg of prednisone daily. Everyone thinks I am crazy, should I seek emergency medical care or wait until I can see a doctor?
