I'm curious about the difference between fibro and MS. I went to my reg Dr. appointment 3 weeks ago, he scheduled an MRI and then referred me to a Nuerologist. The MRI on my lower spine showed bulging discs but nothing else significant. I have a strong tremor in my right arm and have had episodes of uncontrollable shaking (my whole body) and then "blacking out" for a few seconds. I have not fallen down from those episodes but have felt completely exhausted. When I went to the Nuero he ordered a brain MRI and said it looks like MS. Does anyone know if this is typical. I guess I am asking what people think. Its so quick to go to MS in my opinion, since I only got the official dx of Fibro last fall. Thanks everyone.
