Good to read that you are here, Swashy. I hope the next few days are much less difficult.
@MyrtleLion , that picture of your shower takes me back many years, when I broke a bone in my foot and was in plaster to my knee. Our shower had a step like that one. I remember kneeling outside it and leaning in to wash my hair. I can't remember how I kept the rest of me clean, possibly a flannel wash every morning.
The physio taught me how to manage stairs when I was non weight bearing. It definitely involved a banister. I remember it particularly because my office was up a few stairs with no handrail (beautiful old building) so I had to be moved to the only non-specialist room on the site which was on the ground floor.
A colleague lent me her kit for such occasions: all I can remember is a small folding stool which went over my arm, so I never needed to stand for long, and a beaker with a screw top so I could make myself a drink when I was at home alone and not spill it on the way back from the kitchen. In these days of travel mugs you probably have one of those already.
We did hire a wheelchair from the Red Cross, but I only used it once when I very much wanted to go to a particular event.
Even now I have a stool in front of the bathroom sink. It was advised as part of my long Covid recovery, on the principle of saving my energy as much as possible.
Like you, as I expect this situation to be temporary so didn't consider a mobility scooter. However, there's a scheme in the big car park in my town where you can park for 2 or 3 hours and borrow one of their mobility scooters to get around the town centre. It's all free, no Blue Badge necessary. I've only done it once, just to try it out, but it's good to know it's available. I was quite hesitant with it but I saw a couple of women going really fast on theirs. Perhaps there's a similar system near where you live?
