Wow! Welcome to the club. Yes, most docs have no idea what it is. Even the well known cardiologist was hesitant to diagnose it after he ran a bunch of tests and kept saying he couldn’t find anything wrong with my heart. As long as I take the serrapeptase I am pain free.
I should have mentioned that, like my own subsequent heart attack, the “big one” could be in your future.
At least, you’ll be able to recognize it. Don’t let the ER desk hold you up, or the symptoms could ease enough to ignore.
