Geez Twinmom - I haven't done any gynecology in ages, so I looked up the Essure - why on EARTH would they use an insert that has NICKEL in it?????? Nickel allergies are EXTREMELY COMMON (anybody who has ever had irritated ears from their earrings probably has it - see how common hypoallergenic earrings are in the store). It just seems incredibly stupid to put something in the body that has nickel!!!!
I hope they are removing it ASAP and giving you an good old-fashioned tubal ligation instead. And that you get well soon. (((Hug)))
