ok this happened to me tpo, expect i was told to wait two months,
i took them out after for a day, they wereing closing up by the end of the
day when i noticed so i shoved them back through.
after that i waited more than two months till i put new earings in.
actually i ended up waiting 5 extra months, sincce i'd just repierced them (so 2 months plus and extra 3 to be safe) so i would say wait 3-4 moths and you'll be good :)
i dont know why your parlour said 1 month, lobes take AT LEAST two months to heal....
