Hi! I'm twenty years old and am having problems with my pacer. It is a dual chamber, but not a defibrillator. I had the pacemaker implanted in January of 2006. After a lot of pain, I had it relocated to be deeper under the muscle in November of 2007. I was doing okay for a while, but now it's coming back, worse than ever. I have an awful pain on the left side of my chest above my breast where the cite is. The pain also goes right below my underarm on my left side. The pain has recently been radiating down my entire arm to the point where my arm feels week and slightly shaky. When I talked to my cardiologist, he said he couldn't do anything for me. As a waitress, this has been putting a lot of stress on my job since my entire arm is in bad shape. Has anyone else had this problem before?
