I got my IUD mirena insurted on september 2003 I started getting symtoms about four months later I developed a large syst on my left overy it got so large that my ob had to surgecly remove it. About a month later i went back to my ob because i was still experiencing sever abdominal pain at that time he told me that i had endomitriosis i couldnt belive my ears how could a 22 year old healthy woman have endomitriosis i was healthy prior to having the mirena IUD insurted after having this curse insurted i devolped sever problems i know other women are going threw this if any please contact me since i devolped endomitriosis i have had to have a hysterrectumy after living with sever pain for three years i just hope a lawsuite is filed before another woman has to go threw what i did.
