Unsure whether to stretch.

[Dubya182]

I started stretching my right ear and im having an unatural amount of pain. I stretched my left with no problem and that is currently at 12mm. However i think my right may have been pierced on a nerve. Does anyone know if i should continue trying with my right or if i am treading on dangerous ground and should just leave it alone?

I feel like a lot of people have a problem with one ear, for me it was the left. What size do you stretch to? Skipped sizes?
