I agree, go to the hospital, they will pay attention to chest pain. At least let them rule out a heart-attack, a fairly simple procedure and then you can follow up with your medical doctor later. That's what i did when i had pain-twinges in my heart when my dog was sick. I was seen to at the hospital right away and sent on my way when a heart-attack was ruled out and saw my medical doctor later in the week and we concluded it was just anxiety about my dog. My dad died of a heart attack so it's always a concern with me and my medical doctor said i had done the right thing. Hopefully yours is something benign also. Best of luck!
