Hi @pngbee74 Welcome I see your experience some pain in your arm? Interesting I had a pacemaker with defibrillator for about 10 years and can't say I had any pain in my arms. Does your pacemaker so a defibrillator? The kind of pain your describing sounds like a shock but at.least when I had to gets delivered a treatment It was brief and in my chest. I noticed you talked about TKR in another post could it have something to do with that? I'm not familiar with that problem but I also know that pacemakers usually only can affect the heart area . I have heard of people complaining about a strange sensation from the leads of the pacemaker but usually there in around your heart area. The only problem I remember is an itchy type feeling at the pacemaker location . But I also know any issues with the pacemaker itself will be recorded on the device and the EP doctor can check that when they download the pacemaker. Let me know n if I can help further and what type you have.
Blessings
