Nerve conductions symptoms and conditions

I had the Mirena inserted almost 2 years ago. Over the past 6 months, I have had horrible joint pain and swelling in my ankles, knees and hands. I have not been able to wear a wedding ring in 4 months. I hurt so bad that I can't sleep and recently I have felt that my fingers, toes and palms of my hands are cramping. My calves get so swollen, they shine and no one knows why. I have had MRI's, X-rays, innumerable blood tests, nerve conductions and a bone scan. Other than the bone scan showing inflammation, EVERY test is normal.
Because of these increasingly debilitating symptoms, I started wondering if they were related to the Mirena. That is how I found this website.
I had the Mirena removed yesterday and I think I may see some decrease in swelling today. Even though I still hurt, I am not cramped.
I see that many people experience swollen joints, has any one had their fingers swell. My swelling never goes down, I have it 24/7. If so, can anyone share there experience after having the Mirena removed. Did your joint pain and swelling go away?
