Iam feeling in my chest,left shoulder,jaw and back of the heart...

Hi Iam diabatic since february 2018 my age is 31 . iam taking tabs to control my blood sugar levels... From last 1 month i hav pain in my chest and left arm.. i went to dr he did ecg and it was normal my troponin was also normal. dr said u do not have heart problem but still iam feeling pain... what could be the reason? n what should i do??

Those signs COULD be a heart attack,PLEASE see a cardiologist or at least a doctor Good Luck and take them seriously..
