Cindy, This subject has been gone through quite a bit in the
archives so you may find some help there. I would think that it’s
possible that her allergy, being located specifically on her neck
and ears, may actually be due to a chemical reaction between the
sterling and some of her perfumes or colognes, maybe some lotion she
uses in those areas. Can’t say for sure but check those archives.
Lots of things cause reactions, even the foods you eat.
