I'm a male, 47 who was training for my 1st marathon when I had to have a pacemaker put in last Monday. It's been a week and I'm not feeling all that great or wonderful. Everyone told me that I would feel great right away. I am getting better a little at a time but I feel like I have a rock in my chest. My voice has also changed, I have a cough and it hurts to bend over. I also feel the pm kicking at times. I don't want to complain much because I'm grateful for the chance to be healthy. I just don't know what to realistically expect as far as my recovery.
