If you have seen a cardiologist and all heart issues
were ruled out, I can bet your issues
are anxiety related. Anxiety mimics lots of symptoms, heart issues mainly. I have anxiety and my heart races, I get sweaty palms, worrisome, think I am going to pass out and its anxiety. You are pretty young and any CHF is unlikely especially if youve been healthy all this time. Your hernia and acid reflux is likely just that- heartburn etc.
