Here's an exchange I had with a woman in New Zealand:
I know you are unlikely to travel to New Zealand so I went ahead and had a vch piercing performed locally. I thought I had asked the piercer all the right questions but I suspect he has got it wrong. I couldn't find anyone at all who uses a receiving tube but found someone who doesn't use clamps. Thought I was doing the right thing. At the moment I have a 12g ring with captive ball. It has healed well but there is now skin and flesh behind the ring. What should I do? I have a friend who is prepared to redo it for me - what are the risks? She has a copy of your book :) E
Before doing anything else, I'd suggest you get her to lend you the book so that you can become well educated.
I'm not sure what you mean by "there is skin and flesh behind the ring"--can you send a clear, close-up photo or two so I can evaluate your current placement. What makes you think it is placed incorrectly?
If you think yours is improperly placed, that would be a reason to redo it. But if your friend is not a trained professional piercer, I HIGHLY advise against having her pierce you--even if she has a copy of my book (it is not a "how-to-pierce" book!).
