I suffered from this for about
6 months,luckily it has completely gone.
I found that the more I tried to walk normally,the more I tensed up and the worse it got.
I know this is easier said than done but try to relax,thinking about
it made my balance much "wonkier"
I was told that I had started to walk like a robot and I was convinced that it would never resolve itself......but it has,friends and family have commented that I'm moving normally again.
I agree with the others, this was one of my most distressing symptons,at one point I was convinced I had MS, the good news is,it will get better as your treatment begins to kick in
