It will be 6 weeks post-Mirena this Thursday. So, we are in the same situation. I will have good and bad days. The major dizziness and major tingling have stopped, but I still have it somewhat. The anxiety is so hard to get over. I just can't help the way I feel. I have "normal" days and like you said, have days where you just feel crappy. I have a lot of hearburn,digestive issues and a heaviness in my chest that can linger for a few days and then be gone. I still have that feeling of blood rushiing to my chest and throat area. I had an EKG and treadmill test and they were normal. I just wish I new if it was due to the Mirena or if I actually have a "real" problem. I guess only time will tell. I hope we can both post more positive blogs in the near future!
