Omega-3 Improves Your Pet Health

I am 19 year old college student who really has had good health throughout my life. Back in November I was hospitalized due to heart pain, which they chalked up to being paracarditis. A few weeks later the pain went away and I was pain free until February. Since February I have had pain just under the area where my arm and chest meet on the left side. At times I also get a kind of minor numbness pain in my left arm, as well as a weird feeling as if I was excited, and need to catch my breath for a second, like 4 times a month at least. I have gone to all kinds of doctors and gotten all kinds of tests, all of which show I have perfect health and provide no answers. I’ve gotten EKGs, Ecocardio Grams, a Cat Scan or MRI forgot which one, and tried various medicines (mainly anti inflammatory because they thought it was residual inflammation which it was not). I’ve never had anything like this before, and I’m pretty sure no heart problems run in my family other than the occasional high blood pressure relative, and maybe one with a heart murmur. I do get bad cases of heart burn from time to time but have been taking Protonix for a while now to deal with that. Any thoughts, or possible answers??
