For most of this week I have been sick with a cold. In terms of the cold itself, it was far from the most severe I've ever had. However, for the first time (that I can recall), a cold has drastically increased my MS symptoms for a period of time. This included a significant worsening of my "normal" left-side weakness and a return of the balance problems that went away when I had CCSVI treatment in 2010.
My cold is mostly gone, and my symptoms are back to "normal", but it gives me sobering insight into how even a modest worsening of symptoms could greatly decrease quality of life.
