I get little twinges from time to time that I imagine might be my Watchman. But then I think I have gotten twinges in my heart area for a long time. The kind that make me wince and jab my chest with my thumb for a few moments.

I am 100% certain I never feel it. Even right after the procedure I never felt it.

Sounds more like arthritis in the cartilage surrounding the sternum and ribs. My wife has experienced that for several years and she describes it the same way. And if jabbing it with your thumb affects how it feels then it's definitely not your heart or anything deeper than your ribcage.

The only way I "know" i have a Watchman is that I went to Austin to have it installed.....then subsequent TEEs to confirm successful placement.
