Dawn,
I have multiple sclerosis too. Though, at the moment I'm not too bad with it. There were a few months earlier in the year where I was struggling to walk by the end of each day! I needed a shot, or three, of methyl prednisolone. That helped. But, still, if I exert myself, or stand for too long, I do get a bit wibbly!
Variable, really. I have it pretty mild, generally.
Clare.
