I had my Mirena input about 5 months ago. At first all was well, but for the last two months I have had bad anxiety. It took me this long to think it could be my IUD. The anxiety is horrible. My heart races, my arms and hands hurt, and sometimes I feel like I am going crazy! I can not wait to have this IUD removed and I pray after a few months I will be back to normal. I would tell anyone thinking about using Mirena, Don't do it.
