Hello @tplefka. It’s good idea to go to a teaching or specialty hospital, like @erikas has suggested, particularly because the medical professionals you’ve been seeing can’t seem to get to the bottom of your problem. Even if you have to travel some distance to get there, it’s probably still a good idea so that you don’t keep suffering. Have you ever had any lung or breathing issues? Sometimes asthmatic or other lung conditions can mimic cardiac symptoms. Some of your symptoms may be secondary to a particular primary medical condition. Answers are out there, and you just need to be your own best advocate.
