Question: I am back again. I had been feeling better and suddenly morning I felt like my chest was tight and it was hard to breathe which lasted about 2 minutes. I also felt relly hot and sweated until i opened the door to the bathroom (where i had just showered). I came to work and have been feeling dizzy at times and my left pinky and back feel tight again (the way they have in the past) and i feel like i am breathing harder than usual. If you look at my previous posts, you can see yhat i have had testing done both in the ER and by a very good cardiologist (including a CT angiogram, ecgs, and bloodwork). I have had panic attacks but i can't help to fear that this is a real heart issue. Should i go to the ER? Could this be the time it is actually something despite over 5 visits in yhe past 3/4 months?
