Grace,
I think if you are having any pain in the chest area at all, you need to tell your parents immediately so they can have your doctor check it out. This may be nothing at all, but it may be something you should not fool around with. Will you please talk to your mother about it? We care about you here and don't want anything to happen to you.
Please let us know after you talk to your mother, o.k.?
Take care!
Carla
