For sure, go to the doctors and get it all checked out. I have gone through the same thing. I thought I was having a heart attache. I did a stress test, a monitor, and a thorough exam. I was sent to a cardiologist also. Everything checked out fine, but I do still have chest pain. Sometimes it is sharp, runs down my arm, around the back and under my shoulder blade. I was told it's from stress and my ribs being out. It's very scary at times. I also have intermittent heat rate that's off.
Be well
