All MRI results (from brain to lower back) came back negative. I now have very little strenght in my legs. I need assistance getting in and out of bed, the car, getting my clothes on, and what not. Basically, i am using a wheelchair to get around. I had a mylograph which also came back negative. I had one last test done yesterday which is called an SSEP (it tests the electical impulses from the feet to the brain). The results were that there is some blockage somewhere in the spine.
