Hi~ I saw my neurology doc today for treatment of relapse symptoms I'm experiencing. My MRI shows no new spots nor any active plaques. Nonetheless, my balance and vision are off, I have tremors & tingling in my left arm. He wants to do a SINGLE day of IVSM. I've not heard of this before....have any of you? I've done 3 & 5 days before but not one. I'm not having the optic issues I've had before, (besides floaters). I just don't want to do a single day & have to go back for a 3 day later you know? Can anyone provide some info please? Thanks to all!
