I have had two implants. After a year, you will forget it is there.
In the meantime…
Take it easy with exercising and stretching that area. Things are healing. Let it happen.
Stay alert for swelling, redness, or excessive warmth that could indicate an infection.
Good luck !

Just asked your surgeon or if you have a PACE Clinic asked them about restrictions on arm movements and electrical devices.

I don't know what kind of leads put in whether static or screwed in. Also most new ICD/Pacemakers are MRI compliant and much more protective from electrical devices and magnets.

My first ICD/Pacemaker my EP said go back and play tennis. My Pacemaker tech said no don't do that. She warned about tennis and fishing. Anything with drastic quick movements of arms. Well went back to playing tennis (was quite an avid player) and the first pacemaker check after surgery my left lead (that goes to LV) came out and was not working.

Had to have surgery to put the lead back directly on heart and remove the one that came out. So I quit playing tennis after that. I then picked up Sprint Triathlons. Some asked about swimming. I swim very smooth and restrict my left arm and have had no issues when Pace Clinic does check on wires and have been doing them since 2017.

You mentioned golf so just talk to your surgeon and pace clinic. My first LV lead was not put in the spot EP wanted to put it because of veins. The next time he put a new one in my LV he was able to get it where he wanted as Boston Scientific had newer thin wires making it much more easier to get wires in.

You can always go on web site for your manufacturer of your device. They may have information there but most likely will refer you to the surgeon who put it in.
