Hi, newbie here, been on Tysabri 18 months, diagnosed 06. Just now I'm on steroids for first time since starting Ty, two days now, and I swear if anything I'm worse. I'm having trouble finding clear info about differentiating between MS relapse and PML; is it really almost impossible to tell for weeks? Difference seems to be only if you've got optic neuritis or it's fast onset, then definitely MS? An MRI a week ago showed active lesion in brain stem and I'd been having symptoms for a few weeks, steadily increasing all this time. Anyone have any similar experiences or knowledge could help me out? I'd so appreciate that.
But prior, I'd improved dramatically and rapidly after starting Ty--especially cognitively, an area which I'd been hit hard in (my neuro sez about a quarter of MS-ers are hit hard that way, as I am).
