My labs for RA were somewhat elevated but not conclusive. Long story short, I didn't even bother seeing a doctor when the symptoms were at their worst. I believed the Mirena was the cause and the doctor did not so I had it removed. I only used IBU, no other RX. There are just too many cases of autoimmune diseases related to silicone to believe it's just a coincidence. Women with silicone breast implants and the Norplant (nothing more than a differently shaped Mirena implanted in your arm) had the same autoimmune problems. My heart goes out to you. I hope you feel better soon. Keep in touch.
