So glad to have found this thread. I had my Mirena removed 6 weeks ago and for the past 2 weeks or so, I have either woken up with a terrible headache or experienced one at some point during the day. It seems like there are few times during the day when there isn't one in the "background."
This is very unusual for me because I rarely get headaches.
I know this thread is old, but I wondered how long it took for your headaches to go away. I haven't found a place anywhere, except here, that addresses this after effect.
Thanks!
