My 61 year old mother started experiencing vision problems last week, double vision. A couple days later she lost function of her bladder and bowels. She is suffering from muscle spasms and extreme fatigue. She has had an MRI which showed bundles of white matter but not enough to diagnose MS. she has had no prior symptoms. She has had an MRI, cat scan, bone scan, Lyme disease test. Has anyone else experienced this or know of any viruses that can mimic MS? Doctors are at a loss and she has been hospitalized for six days with no answers.
