I've been on Mirena for about 14 months now. For the past 3 months I've experienced this awful allergic reaction on my face. I'm not completely sure it's being caused by the Mirena but it's weird to me that every time I've gotten this rash it's been between the fist and last day of my period. the rash starts with hives on my nose, chin, under my lower lip, and cheeks, and by the next day is blisters that crust over. By the 4th-5th day or so it's just very dry looking skin. It itches and burns so badly though and I don't know if I go through this again. If anyone has any insight PLEASE email me at ******!!!!
