Hi doctor, When I was about 5 I had a heart murmur, it was a hole the size of a pin needle. I had to see a heart doctor a bunch of times when I was young to make sure it was closing on its own, eventually it did. But today I was at the doctors, and she detected a heart murmur. This was the first time in about 11 years that this has happened. I am very concerned, I have a follow up in a month. Can this be another hole?
