progression of ataxia

[Hickox]

I have SCA6. It was diagnosed three years ago. It progressed slowly. Gradually my walking distance shortened, my speech got worse, my balance also got worse. But in the last month it has progressed dramatically. It is difficult to walk without holding onto something and any exertion leaves me weak, and my legs have become wobbly. I am writing to see if anyone else has experienced a rapid change or if I should look to see if something else is going on
