Mirena Shoulder/Back/Neck/Jaw Pain

Hi, I had the Mirena inserted in March 2009, and by the middle of May 2009, the back pain started. Since then, I have had chronic upper back/shoulder/neck pain that won't go away. I am a gym rat, so I thought I had an overuse injury, and was seeing a sports physician, going to PT, etc. PT helped a little, then my back pain got worse. A lightbulb went on last night and I finally realized it may be due to the Mirena. Also about a month ago I started clenching at night or just having jaw tension. Anyhow my body is so tense and full of knots that it is so incredibly painful, and generally I'm in great shape. So I don't understand why I'm feeling this way and why the back pain won't go away. I've seen a lot of posts on this site for this, but I"m wondering 1. do others have this problem, and 2. if they do and removed the Mirena, did they see a difference? ie does the pain go away once the mirena is removed? Oh, I also have what the dr called "snapping hip syndrome"- my left hip is completely out of alignment and snaps or clicks every time I walk. PT told me to stretch, which doesn't do anything for it. Help!
