Hi, I am going through something like this. I had Mirena inserted 2 years ago, and for the past 7 months, I have had severe pulsatile tinnitus(heartbeat sound in my ear all the time). I have headaches, double vision at times, and some headaches. I have a numbness in my arms sometimes. I have been through many tests, MRI, MRA, MRV, CT scan, and a cerebral angiogram. My neuroradiologist suspects Pseudotumor cerebri. I am having the Mirena removed this week. Am wondering how you have been since you had it taken out?
