If you made your ears a size 14 gauge could they go back to normal size?

Iv had my streached for nearly 4 years now and im at a 14mm gauge. I did manage to strink it back down to normal from an 8mm but it did take a few months or so, but i no people that have gone over 10mm and they have returned back to 4-5mm. But it really depends on how elestic your earlobes are and skin.
