I've had a PA for years, got up to 10mm daily, and a 12mm now and then, but it started to migrate.
So, having considered it for a while anyway, got an apadravya a few months ago.
Let me tell you, the pain was real - as compared to the PA, which was barely noticeable - and as for healing, well it never did. I had to go on a course of anti-biotics and remove the BCR. It's just about healed up now, but not a successful piercing, I'm sorry to say.
Still the break it gave my PA piercing seems to have done it good so I'm back to the 10mm tribal dream ring, which is cool.
