I have had a ICD/Pacemaker since 2006. I have 3 replacement surgeries since them.

My Electrophysiologist (EP) said it takes about a year for the device to be encapsulated by body. That include the wires. So think going to get better which body encapsulate it.

I assume from you post your device was put under your skin with wires doing down to your heart. Mine was put under my chest muscle as per my EP my skin was too thin for under skin placement.

With under the skin placement you will notice it more than under muscle. But it takes time to encapsulate and getting seated. You need to follow your doctors directions on limiting movements. Give it time. Make sure you recognized anything that irritates the area or causing it to move.

Even today 8 years after my last device I do not lift my left arm above my head. It irritates the area around my device and can feel a slight movement. So learn to refrain from movements that irritate it or move it and never press on the area.

I will be having my 4 device surgery in less that a year. Millions have the devices and some have pronounced areas under the skin but just remember when you see that know that you have your own EMS there to help you when needed. It is your own 911 system.
