Hello I'm 16 and when I was about the doctor said I had a Heart Mumur when I went in for A Sinus Infection. But when I went in for a Sports physical when I was 13 the doctor didn't say any thing about my Heart Mumur I pasted the Physical. But When I got in High School I started having this like Skipped Heart beats are little Flutters after I play a sport, some times they want happen . I don't really now what it is. And know I'm 16 and now I feel like I'm congested in my left side. I'm going to the doctor Friday and hopefully It want be nothing to serious. Maybe something that can be easily managed :? :(
