I would say that it's definitely the mirena. your story sounds much like mine and others here. I had mine for 6 1/2 years and slowly my health started declining and not one Dr till this day admits that it was the mirena. You can read my story if you click on my name. I'm now 3 years post removal and although I'm not doing 100 % better I'm doing much better than how I was 3 years ago, go figure. I have had so many labs and been to many Drs with no help. I would suggest you to not argue with them just have them take it out and let them know that you strongly believe that mirena was making you sick. The only thing that has come back abnormal in my labs is my ANA (positive) which this has happened to others here. Did they check your ANA?
