Aussiemum, I have also had many of the symptoms you have described. The weakness, joint and muscle pain, muscles twitching, fatigue ect. My Doc wants me to be tested for Lupus and MS but I haven't yet because I've learned from this site that I probably dont have either disease. I am really glad you are going to get this thing out. It may take some time before you feel better. Like Aussiegirl, I also got my energy back after the mirena was out, but other side effects are hanging around. We are here for you if you need support. It has been a difficult road, but many have recovered and we are all working on it together. Good luck to ya.
