I was cleared of a heart attack two months ago at the ER. They did a EKG blood work MRI and a echocardiogram a few weeks later. All test came back normal. I was told that I had a panic attack. I have been having tightness in my chest on the left side above my breast and a burning feeling. I have read that anxiety can cause those feelings. Can something in your heart change in two months. Need help and reassurance that I’m ok.
