I had the mirena for almost 4 years and started having symptoms in July of last year with vertigo, migraines which I never had one before, a vibration in my head blurred vision,numbness,anxiety,also fog brain and neck pain. My headaches would be really weird and extremely painful that I would have to stay in bed for days. I went to so many different Dr's and also had a MRI. I had my IUD removed Sept. 17th and the first week it was out my headache was gone, which I had for 2 1/2 months. I have not had a vertigo episode since but I still have the vibration and numbness in my head and sometimes it moves to my body. Also had my thyroid tested and it is hypo and I am in pre menopaus.I am still don't feel all the way right but every month is getting better. Exercise is helping saving me and eating healthy. I know that my vision will never go back and the mirena caused it. I would really recommend that you have it out as soon as you can.Good Luck!!!
