I had my Mirena removed yesterday due to complications since i had it replaced in May 08. (little to no complications with the first one) The GYN said I now have an infection in my uterus (Endometritis). My symptoms are: lower back ache, headaches, abdominal pain, bloated, nausea, irritability, breast tenderness, fatigue. I got a shot while in the office and am on Doxycyclin Hyc for 10 days. My primary Dr called today with results from a CT Scan done last week due to these symptoms and I have lesions on my liver. I now have an ultra sound scheduled for tomorrow. Listen to your body. If you have the Mirena and do not feel well, please do not put off having it removed. I hope my symptoms will subside soon. I faught to keep this 2nd mirena for 8 months now. I hope I haven't waited to late, and more damage is yet to show up.
