Hi, I used Mirena for seven or eight eight years with great results and no apparent side effects. About two months before discontinuing Mirena, I developed tingling on the left side of my body and much of head. I've had it since October with just a break of a couple of months when my thyroid level and migraine preventative doses were just right. Since it has continued so long after removing Mirena, it is highly unlikely for either to be related. I've had an atypical migraine condition for years which I think is causing mine; all the big things were ruled out. A neurologist that specializes in headaches might be able to really help with your headaches. Tingling is often related to blood flow and nerve damage, plus anxiety. The anxiety type isn't usually on one side, I was told. I hope this was helpful.
