I have two stints in my left descending artery , It was done 2yrs ago. I also have type two diabetics.
I you are certain that the tingling is not caused by the way you were sleeping (with your arm above your head or laying on your arm), I would definately call your physician considering your medical history. Numbness, pain, or tingling in the left arm (and even sometimes in the right arm) can be symptoms of a heart attack. If you experience any of the other symptoms as well, definately go to the emergency department.
