I can't do much for her at the moment as she's away on holiday. She phoned to say that she fell because she didn't see a step, she has problems with downward peripheral vision. The company that she is with has a doctor travelling with them so she is being accompanied to get the arm x-rayed. I haven't heard from her since 11am our time, which I suspect means it's bad news.
So, what would be useful to put in place for her for when she gets back? Is she likely to need help with bathing etc? She's pretty self-sufficient and didn't need much help when she had a knee replacement for instance, but she's 81 now and probably likely to heal more slowly than when she had her knee done a decade ago.
