Well, for me it's my new norm. I avoid stairs like the plague! Weakness is especially prominent in my left leg and my right arm.

But......MS treats everyone differently and some may have no obvious weakness in their legs but lots of visual issues. Or no visual issues but lots of numbness and/or pain in their arms and legs. And some of us are blessed with all of it!
It's hard being in limbo and not knowing what's causing all the strange symptoms. Have you been to a Neuro that specializes in MS? What testing have you had? Sometimes it takes quite a while to narrow it down and get that diagnosis. Lots of other things mimic MS so it's not a quick process.
