When I was thirteen, the doc told me I had heart murmurs and it kinda scared me but she told me that heart murmurs arn't really nothing to worry about. She said my heart was still healthy but it affects a lot of kids. But when I was thirteen I had troubles with my heart feeling funny and now that I'm 17 sometimes it behaves the same way but not as much as it use to. Do people with heart murmurs have higher risk of heart problems when they are older?
