I think it is very possible that the Mirena is causing the joint clicking and muscle spasm as well as weight gain, acne, mood swings and migraines. I thought my fibromyalgia had been improving before I had this inserted but as I read more and more on this site I am doubting that. I want to have it removed but I don't even want to go back to my same gun who would have put this into me in the first place. Can a different Dr take it out than put it in?
