Sounds to me like you never twisted and played with your earrings, so while the hole was healing, skin probably grew around and attached to your earrings.
I would go see the doctor and have them take a look at it, they can remove the earrings for you safely.
And it was stated here that they still can be removed, plus it was three years ago, PLUS some of them might have been given in error, since there was some stupid thing back then that you wouldn't really know about.
