Any hikers out there hiking and using a backpack with a pacemaker? Tuesday I had to have a pacemaker put in and when discussing my goals with the doctor I mentioned I like to hike and can't wait to get started again, well he informed me that the use of a backpack might not work. I explained the weight rides on your hip not shoulders but he said it's the strap movement or rubbing that's dangerous. Any advice will be appreciated.
