Thanks for all the replies.

It's better today. I think Joelle is right about gait being the reason for it. My gait is horrible. And, strangely enough, using my cane makes it even worse! Sometimes it seems like the cane makes it harder to walk...if that makes any sense.

I walk best behind a grocery cart - which tells me that a rollator would probably work well for me. I'm just not (mentally) ready for that yet. I rarely go anywhere except the grocery store anymore. Walking here at home doesn't seem to be a big problem. I have lots of things to hang onto and usually travel the same "path" throughout the day.
