I feel very sorry for you Loved1. I'am still going through this today. I don't go the the hospital anymore because I'm tired of being told they can't find anything wrong. I told my cardiologist the last time I saw him that this chest pain and trouble breathing use to be frustrating. It is beyond that anymore. I have had thirty-eight heart caths. I have fifteen stents, a pacemaker and had 5 angioplasty's. I know I have unstable angina and that is a problem. But this chest pain is ridiculous to the point I' am ready to just give up.
