I've been having this weird discomfort in my upper left chest for a while now. So, I went to a cardiologist and did all the tests like ECHO, ECG, and TMT, which thankfully came back normal. The doc said it might just be muscular pain, and they also found out I have a Vitamin D3 deficiency, so I'm on tablets for that. Plus, they advised me to lose some weight since I'm considered overweight. But there's something nagging at me from my ECHO report it mentions "trivial tricuspid regurgitation" and "trivial mitral regurgitation." I asked the doctor, and he said it's not a big deal, but I can't help but worry. What do those terms mean, and should I be concerned about it getting worse?

Trivial means minimal which is negligible,no need to worry about ir 8 out 10 people will have such report and its not significant,maintain healthy lifestyle and follow your doctors advice
