What a shame! Earrings are my favorite jewelry - I would not look
right without them. So I really feel for you.
“Feel” for real, as well. Wore thicker-than-usual ear-posts in one
set of earholes last week, and the earholes are still sore & swollen.
I work in enamels too, and I believe that the extra material would
make it too bulky to wear comformtably (unless your piercings were
done a long time ago and have sagged just a bit). So far as
durabilitiy is concerned, I think it would be fine, as the
earposts/wires are not heavily stressed during wear…just getting
them in that would be a problem.
It almost sounds like you have a form of contact dermatitis, and
that anything would irritate your ears. Try getting some OTC
strength hydrocortisone creme (comes in a tube) at a drugstore, and
put a bit on the end of the wire/post before you put in the earring.
See if that reduces your problems.
Good luck to you,
