I haven't been diagnosed w MS but I had a recent crani for an aneurysm repair on my frontal lobe. All the fatigue symptoms I've read here sound like mine. I'm 9 months post surgery and seem to be getting worse w this instead of better. It is very frustrating and leads to deep depression for which I was already being treated for before surgery. I don't hv any answers for you but do somewhat understand what ur going thru
