My 6 year old daugther was born with a heart murmur, I was told she would grow out of if. She has never had a problem until now, She has been coming home from school everday with chest pain. So I brought her to the doctor today and she said it is either acid reflux or something to do with the heart murmur (that I thought went away). What do you thing it could be? She is having the pain after lunch (baked potatoe and bar-b-q everyday) and then she goes to P.E. and then the nurse.... No fever, no vomiting.
