Susan,
I have mitral valve prolapse also, and I have no symptoms from that, but I have went to the ER over the pain from acid reflux. I know how bad it hurts. If it continues I would call your dr, do you take anything for acid reflux, even my father called me a couple weeks ago, and the pain scared him, and it was not his heart. But always call your dr if you are worried. We can support each other but sometimes we have to turn to our drs.
