I have sharp pains in my chest, whats wrong?

I'm 14, and dont smoke or anything, and have been getting sharp pains in my chest. they usually go away when i eat something, but this time they arent going away..i have taken 2 tylenol, and 3 tums...and the pain is constant, but will let up every 5 minutes..it really hurts and i think somethin might be wrong with me..my mom just says its heartburn, but i doubt it hurts this bad and for this long..

Yea that happened to me to im 16
the doctor said its organs i nthe body streching do to growing and what happens it it leaves air bubbles so to speak in your thoracic cavity beneath your heart
so its actually just air or gas so to speak
dont worry
