Hi,
I have been struggling with nausea along with body numbness for two months now. I got Mirena the end of January 2010, two months after having my son. I too am wondering if it could be due to the Mirena. I am currently going through testing to rule out MS. Very scary! I sometimes feel like I feel when I am pregnant, or I feel car sick. Is that how you would descibe your nausea? Occasionally I feel kind of dizzy, like if I turn my head too fast, it makes me sick. Have you asked your doctor about your symptoms? Good luck. Let us know if you find anything out.
