Oh honey I feel your pain, literally. I started having chest pains and left arm pain, well really the whole left side of my body, right after I had my fourth son. I'm fairly young like you so naturally I panicked and took my *** to the ER. All kinds of tests were run and NOTHING, NADA, ZILCH was revealed abnormal. But to be honest, most doctors don't give a real crap about young people with chest pains because it's not a common problem. I think it is very rude of doctors to just shine us off and tell us it's from stress or something. Yeah........Right. I feel for you and I'm hoping the full physical I am going in for clears me of anything. But, if you ever need to talk or vent, I'm here.
