I got just one done back in February. It was also 14 gauge...must be the standard size they do? I did ok, and then as soon as I sat up after the piercer did his thing, I said "I'm....gonna lay back down". Haha and then 5 minutes later I was fine, but I think it was the adrenaline!
Was painful for maybe a week or two, and a month afterward, if I hit it pretty hard, it was pretty painful, but only if my dumbass provoked it.
