I had one put in May of this year, was diagnosed with MS in August and my Mirena fell out in November by itself. It was suppose to last 5 years and only lasted 6 months. Came out after I started treatment for MS.
Could be a coincidence or not? Who knows?
Might want to check with your doctor just to get you some answers.
Best of luck to you.
Have you checked with your gynecologist? It would be a stretch for an IUD to cause neurological symptoms unledd your blood was getting poisoned in some way. Perhaps infection? IYour symptoms may have another cause.
