Hi..I had my Mirena for 3 years and 4-5months. I had little problems until around 2 years 7-8 months in. Then my eye started twitching and mild anxiety. then a few months later, weird heart feeling, along with major feelings of adrenaline rushes(for no apparent reason), as well as the tingling,numby feeling. I am now 3 1/2 months post and feel a little better, but think I had my 4 month crash early. Hope you feel better!!!
