Dr. said i had chest wall pain and a swollen chest wall.perscribed me prezidone a few pain meds and in two days feeling so much better.why they didnt do this on my first visit to the er im not sure,but my pain wasnt as bad.it was tolerable.second visit,i felt pain i neever want to feel again.how do u stop or control sweeling in ur chest wall? my mom had a tripple bypass three or four years younger than me and i am 51.she is now passed.im terified of a heart attack after seeing what she indured. thank you so much and God Bless You
