I had a very serious infection which provoked, what I felt was, an equally serious MS flair. My legs would crumble beneath me, and my son had to pick me up off the floor more than once. There were times I even lost the ability to sit up. I would flop backwards on the bed and wait until I could sit up again. One day it took me at least a half hour to crawl to my computers in here. I wasn't even able to crawl that well either. I started calling these episodes, "spending quality face-time with the floor."
Does anyone know any details as to how infection impacts MS? I have secondary progressive.
In any case, call a doctor when you get sick. I will from now on.
