It will get better
My sympathies for your current pain. I got a pacemaker about 9 months ago.
i had similar pain that you are experiencing. For me, it got better in a week, and significantly better in 3 weeks. I felt well enough to go back to ( driving myself)
your time frame may be different than mine. The main thing is to remember getting a pacemaker these days is very common place. You should heal up nicely in a few weeks. If pain persists, call your doctor, he may be able to
give you something for the pain. Usually after a few weeks you should be feeling better. It is a surgerical procedure, so don’t be cautious asking your doctor for something for the pain. I love how I feel know. I bet you will eventually love yours.
