I am new to this forum and was doing an internet search to help me figure out what is causing me to have these wierd symptoms...when I thought maybe it's my Mirena?? I have had it since March 2007 and in August I started developing lightheadedness, then subsequently tingling in my hands and feet. I have had an MRI of my head and an due for one next week of my cervical spine as my Dr thinks this is MS??? I'm freaking out and after reading all of your posts, I think I just want to get this mirena out! Has anyone had similar MS type symptoms develop while they have the Mirena??thanks so much for your help!
