Eighteen wheeler symptoms and conditions

I know that so many of you have said it but I will say it again: THANK GOD I'M NOT ALONE!!!! I thought that I was going mad! Im a 27 year old mother of 3 and decided to get the Mirena because it seemed soooo easy. What was not to like??? 5 years of worry free sex?!?!? Sign me up!!! Well, I had it inserted Sept of 08 and it did not hurt as much as I anticipated (that was a relief). First of all, I bled what seems like nonstop for the first 5 months. Right when I was thinking about having it removed due to the bleeding, it stopped! Suddenly! That made me very happy. But yesterday, as I laid on the couch, in pain, watching my kids destroy the house and helpless to do anything to stop them due to pain and lack of energy, I started thinking really really hard. I said to myself 'self, something is not adding up here'. It suddenly dawned on me that my chest pain, intense lower back pain, my right side hurting so bad that sometime I can hardly stand it to walk, coincidentally started shortly after having the Mirena inserted. The more I thought about it the more it made sense! You see, I have never been a sickly person (thank God!) hardly ever had a headache. But for the first time in my life, I felt as if my body was falling apart!!! I woke up every morning feeling as if I was ran over by an eighteen wheeler! I mean, sometimes I can't even function well enough to get through the day. This is causing so much stress on my children, my fiancee, my school, and work! Everyone (including my DR) thinks that its just stress and that I have too much on my plate. I accepted that for a long time and struggled to simplify things. My Dr. has tried Naproxen for my chest pain, muscle relaxers for what he thinks are pinched nerves causing my backache and stiff neck. But dude, seriously... its getting worst! And besides I do not want to take 50 pills everyday just to function! SO here I am researching side effects and BAM!!! So many women are experiencing the same symptoms. So 1st and for most, thank you all for sharing your experiences. Now I know what is ailing me. But Im not sure that I want to take it out because I love the freedom that comes with the Mirena. I will talk to my doctor about ways to manage or eliminate my symptoms if possible. Does anyone know of another worry-free birth control method? Other than abstinence :-)
