This is my first time posting on here. I have been worrying about my heart ever since I went to the ER three months ago. I had a EKG blood work CT scan. All test came back normal. Then I had a echocardiogram and a nuclear stress test. All came back normal. I am not sleeping good at night due to worrying that something in my heart has changed since having all the test done. I am dealing with anxiety. Doctors have told me that I’m ok and that my heart is good. I have been having tightness on the left side of my chest and a burning feeling on my left side. It makes me worry more. I don’t know what to do.
