"if you are thinking of having this fitted then please consider thinking again. i&#039;ve just got out of hospital after my gp perforated my uterus during fitting 4 days ago. the insertion was excruciating and i&#039;m not exactly soft! took four attempts to get it in place. one day after insertion i got an episode of trigeminal neuralgia down the right side of my body which i have never experienced in my life. 3 days after that i started with what felt like a kidney stone but after 12 hours in hospital turned out to be perforated uterus on top of a kidney infection. i seriously think all these side effects are related to the mirena coil fitting although i&#039;m sure medical professionals will beg to differ."
