I am interested, too. I started tailbone pain about 2 weeks before Mirena was removed from my gut, where it had embedded. MOST of the tailbone pain went away a few days afterwards, but some remains. Also, my back hurts about 4 inches above my tailbone and has for 10 months (5 months before removal and the 5 months after.) Since removal I've had left pelvic pain as well, off and on. I had a CT scan today to look for answers.
