hi.i just experience an on and off chestpain lasting for 15-20 minutes,the first day and subsided.took aspirin and slept the whole night. Had to wake up early for work,it happened again maybe for 5 minute,pressure on left sideof my chest,and gone to work. During lunch hour it came back and iiit radiates to my shoulder and slowly down to my left arm.I am not too worried thinking if this is reall a heart attack i will be dead by now.It was my co worker who insisted me to go to occ health. I had a very bad family history.My mom died of stroke,dad died of right ventricular failure,my sister died at age 47 of heart attack,and in family side two died of stroke,tripple bypass in early age.In ER my Ecg,chest X ray and blood work is normak and i'm feeling like an idiot waiting for them to tell me that everything is normal. I reall dont know what to do now. Would you mind telling mr whats the next step i have to do. Thanks in advance
