I am on my second mirena. The first one was overall very good to me. This one though, I've had for 2-3 years cant remember exactly when I got it put in. But I have been having chronic headaches to migraines for just over 2 years now & have tried things from advil ect to chiropractic care to botox to no help. & was told that maybe it's my mirena. Has anyone else had this? Hy headaches are usually always sever.
