I had the Mirena removed 10 months ago because of dizziness and constant lightheadedness. My dizziness did get worse before it got better. The first 2 weeks post-removal I felt so much better and then Bam! The dizziness hit me like a ton a bricks. I couldn't even get out of bed without the room spinning. I'm assuming it was the crash. Since then, the dizziness comes and goes with no pattern. But I am happy to report that I've had 4 straight days now with NO dizziness or lightheadedness. This is the longest stretch I've felt normal since before I got that evil thing. Good luck to you and it WILL get better.
