in the center of my chest, offset to the right from where my heart is.
So is the pain occurring directly in the center? If so that is where your heart is. Contrary to what most people seem to believe, the heart is the center of your chest, it isn't offset to the left at all.
Regardless, you should at least get it checked, reoccuring crushing pain isn't something to mess with. It could be nothing but I'd want to be sure.
