Yes! It is a thing! My grand dad had it too. For me it feels like a super tight muscle cramp from my left shoulder blade, through my heart region, and out to the outside of my chest >.< It even goes down my shoulder and into the upper part of my left arm which is what freaks me out that I'm having a heart attack XD
ANYWAYS! I'm glad you are ok and you are a mega punk for making me worry!
