Back in January through April I was having severe chest pains, shortness of breath, etc. but repeated ER visits and my cardiologist seemed to find nothing wrong with my heart. Started taking beta-blockers for anxiety (caused by symptoms, not the other way around) and palpitations.
Despite the positive tests I've still had the pains and shortness of breath. Intermittent pains and SOB between April and now. I began exercising again a few days ago, and had to stop after ten minutes because my chest hurt and I could barely breathe. No SOB as I write this, but seems to come back with exertion. Weak/fluttery pulse sometimes also, usually at night when falling asleep.
Could this be related to some early-stage, early-onset heart failure? I'm interested to hear anyone's speculations. Heart damage in the young is hard to detect.
More extensive accounts of everything I've gone through can be found here: http://ehealthforum.com/health/do-i-have-myocarditis-t386303.html (I was worried earlier in the year about experiencing symptoms caused by myocarditis, and suppose I still am.)
And here, too: http://www.reddit.com/r/Health/comments/19lr0q/calling_all_cardiologists_heart_problems/
I also had an echo in February that showed my heart working normally (LVEF 65%). But I wonder if things could've changed between now and then.
Thanks for your advice.
