Sorry for the random question but I thought you ladies might be able to help. Up until a couple of months ago I have never had any sensitivity problems with my ears and I have worn earrings everyday for, I don't know, the last 20 years. Every once in awhile I might get a little irritation if I wore fake earrings for several days in a row but nothing serious. Lately I haven't been able to wear them because everytime I do my ears scab and itch. I have worn nothing but sterling or gold, any suggestions to what could be causing this and how to fix it?
