Has anyone had an allergic reaction to mirena? Is this just me. I cant figure out if I am allergic to silicone or the fake progesterone. I had hives that started on my trunk and moved to my limbs. It appeared that I had chicken pox and hives all over my skin. The doctors thought I had an immune difficiency. I pulled out the mirena and I cleaeed up in 10 days. Has anyone else experienced this?
