I posted a month or so ago that I was having my Mirena removed. I did and within a week there was a noticeable difference in my energy and attitude! Then my hands and feet deflated from the swelling - Thank God! The low back pain is gone, my blood pressure has lowered, I've lost a bit of weight, the cramping/pain in my lower abdomen is gone...
If you are looking for reasons to have one, do more research before you do... If you are considering having to removed because of similar side effects, you need to make your own decision... but in my opinion I would have it removed.
