I bumped my pacemaker yesterday while hugging a friend and it hurt. Now the site and everything around it hurts. If I damaged the leads or anything how would I know? And how much tylenol can I take for the pain? I just received this 6 weeks ago so I'm totally new at this. My arm pit hurts in the crease by my shoulder. Is that normal too? This is all new to me and pain is bad. Will it get better or should i go to the urgent care? I'm not liking this thing in my chest although it's helping. HELP!!!
