@chas521 I’m going by what others have said too. If you have time, read the various comments in this thread:
Outside or inside?
Many people say similar to what I said - though you said different on that occasion There is a comment from phall there.
“I asked my Neurologist why and she said that I know exactly where to touch in my home and yard regaining balance and outside my home I am lost. If I can get to a shopping cart, I am graceful and safe. Let go of the handle and I fall! Take risks but be careful, another balancing act.”
That comment in particular was very convincing. I noted too that his story is very similar to mine. I often look at people’s stories - where they live, why they have ataxia etc. I see that you have an SCA but which number is it?
