Aw! Most of us can certainly empathize with you. It's not fun and kind of scary when that happens. I've had a slow build up to it and a sudden, legs don't want to function/move. The sudden ones are the worst because there is not planning involved. At least if I can feel the muscle fatigue before doing something I can choose whether or not to actually do it.

I use a cane most of the time when going out walking but some days I need to use the walker (rollator). I do fine with the cane for shorter distances when I am not have balance issues or walking difficulties. Longer distances, it's the cane. In the stores, I use the motorized carts if they have them. It makes shopping so much easier!!! If they don't have motorized carts, I have to use the shopping cart as my "walker" and the trips in those stores are usually short, like get what I need and get out kind of short, unless I'm having a particularly good day. Definitely consider getting both the cane and the rollator. I don't know what insurance you have but check to see if they cover the cost of the rollator. Your doctor can write a script for it if it is covered.

I hope you are doing better!
