I cannot believe that I found this site. I just had yet another symptom pop up within the last few days -- joint pain. The pain is so extreme. I got my Mirena put in April 13, 2009 and it's been awful. I also have a sensitive cervix and bled all over the table and it was so extreme that the nurse had to use a handful of nitrix things to cautirize the area. Anyways, I was lucky that after my third child that I lost the weight almost immediately. I also have a low thyroid, which makes the weight loss all the more remarkable. I had the Mirena put in 2 months after having my son. I haven't stopped bleeding. I experience both the red and brown blood. I'm passing blood clots daily. I get light-headed and put on 10 pounds in 4 days. My hair is falling out. I have horrible abdominal pain, lower back pain and feel overall pretty lousy. As if my symptoms weren't enough to discourage intimate relations the severe bleeding any time we do have relations would. I surely thought that these symptoms were from my thyroid. I just had it tested. My levels were actually in the hyperthyroid range at 0.3 -- it's never been that low. Now, I'm wondering if like a lot of you that the MIRENA may be to blame. It's ridiculous how awful and woozy I feel. I haven't felt this bad ever!
