Cms22; I am sorry to hear that you're having problems with this horrible IUD. Your symptoms i know them to well. I had the samething happened to me last cycle. The worst thing about this I was driving a 7hr trip. All of a sudden I had that same feeling. I also thought i was having a stroke & I panic even more my vision went blurry, heart was raising, side of my face went numb I had to pull over and breath, relax sigh...eventually this feeling went away.
