I have a question regarding the mirena IUD. I got it inserted at the end of August. About a week later, I got a virus and subsequently bronchitis. A week after that, I had my first asthma attack in 10 years. I have had chest X-rays and a ct scan of my sinuses in the past two weeks. Both negative for anything. I have had difficulty breathing, tightness in my chest, and constant shortness of breath. Could the Mirena be causing the shortness of breath?
