My stepdad who is 63 and has 5 previous heart attacks with 12 stents, started having pain in his left arm yesterday around 6pm, he can barely raise it. He says it doesn't feel like when he had his other heart attacks but today he hasn't been making much sense. My mother thinks it is because he hasn't gotten any sleep but I'm concerned. Is there anything I should watch for because they both don't want to call an ambulance or go to the doctor.
