Hi, I Never Been To A Site Like This, But

Hi, I never been to a site like this, but curious as to what feedback I can get. I have chest pain, but it only hurts if I move my arms or move a certain way period. It does not hurt when breathe cough or when performing vigorous activity. I noticed a while ago that when i slouched a certain way my chest had a faint pain but would go away when i'm relaxed. I have 4 children and I always held them all the time no matter how heavy. Should I be worried?
