I have noticed that I can't sleep on any one side too long or else my arms fall asleep. I find myself lying flat on my back. I get alot of tension in my neck when I drive for too long. All of this makes me nervous, I had mirena for over 3 years. I had minor issues that I now know were from Mirena, but the really bad symptoms didn't start until I reached the 2 year or so mark. I wish I had found this site before then. Glad I have it now, it really helps to talk to people who understand! Thanks!
