could i be having a heart attack?

i started working out a week ago on Monday and on Saturday night i noticed my right arm was hurting but if was on and off pain, i thought i had a bruise which i didn’t also it wasn’t sore pain cause of working out.. today is hurting again and it feels so weird like tingling but not that type of tingling as when your arms fall asleep.. im not sure what it is but its only my right arm everytime i google it up it says heart attack but i don’t wanna worry too much
