Trivial TR and MR. Get severe in future?

Dear Doctor, I'm 33 years old man, I often get some discomfort in upper left chest. I went to a cardiologist and took all relevant tests. My ECHO, ECG and TMT were normal. And doctor concluded it should be a muscular pain. Also I have vitamin D3 deficiency and they prescribed me tablets for that. Also doctor suggested me to lose some weight since I fall under over weight category. My question is all though everything looks normal it was mentioned in my ECHO report like trivial tricuspid regurgitation and trivial mitral regurgitation. I asked doctor about this he said it is not cause of concern. But I'm little worried. What do they mean by trivial TR and MR??? kindly answer me. Will this condition progress and get severe in future?
