My OBGYN told me flat out there were "no side effect" from the mirena, both at insertion as well as when I had it removed 6 weeks ago. (even though he had to have recieved the update from the fda listing all the side effects). although i feel crappy today, (which is why I am posting so much) I am soooo much better than when it was in. I just posted under the class action suit section all my symptoms, so I wont repeat. There is a SLEW of research discounting what your doc is saying, and many docs who disagree with him-find one of them! It took me 4 1/2 years to figure out what was going on-no thanks to my ex docs (I have found new one, who agree with me)-and I can never get that time with my children/hubbie back. the symptoms are progressive, and get worse...MUCH worse in most cases.
