I am a 15 year old girl who has been experiencing bad chest pains in the morning, mainly when I take a deep breath . It hurts in the same area as my heart is, making me think that it is my heart that is hurting. Sometimes it will last throughout the day up until I go back to sleep. I don t have a bad health history, but I haven t gone to see a doctor for quite sometime. As a child, I was around cigarette smoke a lot, so maybe it would have something to do with this? Thanks
