I suffered from acid reflux years prior to Mirena but with the help of a gastroenterologist and changes in my diet, I got it under control. I got the Mirena IUD placed Sept 2013 and got it removed after a year. Prior to the removal, the acid reflux was back. It felt as if something was stuck in my chest. Also prior to Mirena, I never suffered from anxiety or panic attacks which has now become a normal feeling since Mirena has entered my life. Just know you aren't alone. I just got my second period post removal and I am crashing hard! My anxiety is at a all time high, I can't sleep, and the racing thoughts are getting the best of me. The reflux and heartburn came back pretty hard along with my period. This crash feels just like when the IUD was still in me! I pray that I will be able to look back at this as a huge bump in the road and that things start to smooth out soon. Keep your head up and God bless.
