@OmSigDAVID,
I have
this.
It's not a mental problem, but what's funny is that even if I'd known about it beforehand, I'd probably have had my ears pierced anyway. It just means I'm doomed to not being able to wear the pretty, less expensive jewelry many others can. The ear area is the most sensitive, but my wrist and neck areas will become uncomfortable if I wear cheap watches or necklaces. I mostly just go bare (those gimmicky 'cures' -- stainless steel, plastic shields, dabbing on special ointments -- don't work).
It's the second most common allergy next to poinson ivy. I can't imagine having it on my tongue, or, er, other body parts lol.
