Mirena and numbness in legs

Well Hello everyone. I am glad I came across this site, because I thought I was going crazy...I am 35 and just had my first child March 2007. I have had the Mirena for a year now. I went to the Dr. a few weeks ago and told her I was feeling sharp pains once and a while, but other than that I felt fine. She ordered an ultra sound and they found some small cysts...so I go back for a recheck 6 weeks from that date to see if it's gone away?? That did not make sense to me....she said I also had a yeast infection (which I have never had), and pre-cancerous cells which she is biopsying next week. What I thought was completely unrelated was my back pain-sharp siatica pains and my numbness in legs, feet, arms, and hands...my friend told me I should see a neurologist...and I almost started down that road....until now...I think I will have the Mirena out first and see what happens. I also have some twitching in my fingers. I will let you know how I feel after it's out. Oh and Mood Swings....I always have this feeling that I don't know what to do....everything seems like too much!
