You have just experienced the Mirena crash! No OBGYN will admit it because they worry about liability. I had mine in for 2 years and now 2 months post Mirena. At 6 weeks post, I was taken to the ERIC for chest pains, dizziness, and numbness in my hands and feet. I was released saying I was having an anxiety attack! It's such BS! I was having a good day until, I had to sit down because I was so extremely exhausted I couldn't move, then all the other symptoms came. I was experiencing the crash. And boy did I crash. I feel better now and the anxiety has subsided. The only thing I am still left with is the horrible itching all over my body. Still waiting for some relief. Good luck and no you are not crazy.
