what does it mean when you have a murmur in your heart? I went to the doctor for my headaches, and instead found something with my heart. They said that they could hear a murmur inside it. And they did an AKG on me, and said that it wasn t too good. So theyre sending me to a cardiologist, and now im kind of scared as to what the murmur could be inside my heart... What could it be? Ok, of all the times that I ve been to the doctor, they ve never noticed this murmur in my heart, and now it just appeard out of no where? Its kinda weird, plus still is freaky...
