Not a thing. Never wanted anything pierced, ever.
But, I did receive an earring-like injury. A foster cat sliced open my earlobe, just like an earring being pulled out, except it only went 75% of the way through. Of course, it was a weekend night, and I didn't want to go to emergency, so I just hoped it would spackle itself together again, and it did.
Couldn't feel much of anything on that lobe, for months.

What did I learn?

I still don't want piercings.
And don't get in the middle of a cat fight.
