"With in a period of 4 years I have had 2 mirena inserted.  First insert was definitely as painful as a full contraction.
The benefits I received by the mirena was:
My skin condition  has calmed,  severe cramping had lessened,  bleeding wasn&#039;t as heavy.
After stating this shortly after the first insert I became ill was was diagnosed with a auto immune disease and sero negative rheumatoid arthritis. 
Even though there is no study or theory base evidence to suggest that the mirena had any cause to kick off this condition,  I strongly personally believe that my body&#039;s response to both insertion of the mirenas has it tricked into my immune system trying to reject the mirena being a foreign object inside my body. 
I currently can&#039;t take it out"
