I just had my IUD removed this morning after reading many posts with similar problems as mine. I had my IUD in for about 5 months now. This month and the previous month, I had been experiencing extreme chest pains (directly in the middle of the my chest) with increased pain with breathing. From this pain, I had panic attacks (which I had never had in my life previously). No problems with my heart at all. Had to go by ambulance to ER and during the 5 hours, the pain went away... They only checked my heart, even though I never thought it was my heart, since it was in the middle of my chest... Movement increased pain, as well. I would feel rushes of warmth and heavy vomiting. After my 2nd episode, I began to realize that my previous episode was also during my menstrual period, which led me to believe that it may have something to do with the IUD. Since both my last two cycles were extremely light flows (barely anything really)... My hair was also falling out a lot after having the IUD.
