I was hit in the rt side of my chest at the top of my breast 2 days ago and since then i've been having sharp pains. It increases when i try to take a deep breath or lay on either side. I wasnt hit that hard, there was no bruising. I am 38 years old and in good health otherwise. I am a smoker and have a family history of heart disease but this doesn't feel like heart it feels more like lung my pulse is normal
