I'm not sure if the Mirena triggers MS or not, but just KNOW that you are not alone in your symptoms. ALL of us on here have had those symptoms. I just had an MRI Saturday. I am waiting for the results. My symptoms are way better. Just to encourage you, I don't know of any of these girls who have had these symptoms who have had a positive diagnosis of MS. It's just that the symptoms mirror those of MS so closely that neurologists THINK that it is. Keep us posted. You're in our prayers!
