Our son is 17 years of age has had a funcitonal heart murmur since he was 2 years. He is very active an outdoor kind of kid. In the last three years has complain of chest pain. It came and went so fast and was extremely intense while it lasted. We didn't think anything of it because we associated it with indigestine, because it happened maybe once in eight months. Last night after eating he had another one. We asked him when the last time was that he had had one and he said about three weeks ago. He aslo said they were starting to get closer in from time to time not nessicerally duration. Please reply if you have any answers for us.
