I found this a while back for a friend. There may be light at the end of the ...erm.. tunnel.
{Will the hole shrink back?
The answer to this depends on lots of factors.
Generally though, holes of up to about 6mm or 8mm, and even sometimes as large as 10mm and 12mm, will shrink back down to normal piecing size. (Given enough time)
I do know someone who had stretches of 20mm, which shrunk back to almost nothing. He had very elastic ears.
The factors that affect this are;
How quickly you stretched up... too fast is bad as you can build up scar tissue that might not stretch back down.
How long you rest between each stretch... same reasons as above.
Your skin elasticity... everyone is different.
So, unfortunately, there is no definite answer, everybodys ears react differently to stretching.
Ear stretching is a permanant body modification and as such should be taken seriously. Some Body modders would say if youre already thinking about shrinking your holes, dont bother stretching in the first place. In any case, dont rely on the fact that the holes will disappear.. they may not}
