I went to a DMD the other day to have a consult about my wisdom teeth and because having them taken out is minor surgery, he had to check my heart and said I had a heart murmur. I am 15 and until yesterday no one had noticed anything. not even my PCP. I had a physical last week and he said everything was fine. Is it odd that people are just starting to notice that I have it or is it just a random event ? I am getting an echo tomorrow to make sure that it is nothing big. I m not too concerned though.
