Shift.ms is better if you're logged in

So I took my 2nd year of mavenclad over a year ago… and have not had an mri in 3 years now. I have recently started experiencing vision issues that last a week or so then go away only to come back a few weeks later. I also have had some muscle weakness during the same time. Is this something I should be alarmed about or is it normal for RRMS? I didn’t have these symptoms before.
