"i had mirena inserted in june 2015. the insertion  process was very painful. i had a local anesthetic, and the doctor said it reduced the pain 50%. the pain of the sound for uterine measuring was significant despite the anesthetic. i experienced some bleeding and severe cramps with rectal pain and pressure for 9 days.  i spent most of the 9 days heavily medicated and missing work. i could not sit down without extreme pain. this is not a normal reaction, so i should have removed it right away. after ultrasound the iud appeared to be properly placed. the conclusion was that mirena was either poking or aggravating a major nerve. had mirena removed after 9 days. symptoms improved immediately upon removal but not completely resolved yet."
