"i used the mirena as a contraception and as a way to control my uterine bleeding. was an effective contraception however it did have intolerable side effects. on a positive note i was less mood swingy and weight loss. on the more negative side i felt gradually mildly depressed had a severely reduced energy.  six weeks after i had the coil inserted i began to have upper back pain, muscle tension which got increasingly worse.  i was getting by by popping pain killers and attending physio, nothing helped. i finally realised i only ever had a bad back since the coil and muscle tension and bad back are listed as side effects, after 7 months i had it removed within 4 weeks my back pan had gone, i felt so relieved. never again. i have my energy back as well."
