Hi
Littlejem - You're smart not to do those stairs alone just yet. The first week I was home, I got up early when my husband was still home, and he helped me shower and dress, etc. and settled me downstairs on the couch with everything at hand before he left. I'm lucky to have a bathroom downstairs, though. A commode or portapotty would be what you'd need downstairs in order to stay there all day. Can you rent one from a medical supply place, or do you have thrift stores that are likely to carry them? I have one that was previously used and I just bleached it to death before I got near it, although it was nice and clean anyway.
The stairs were tricky for about a week for me, and I was weak so I always had someone with me to do them. You might feel comfortable doing them alone sooner because I had both hips done at once, too.
It all happened to you so quick, you didn't have much time to prepare, did you? I started getting supplies months before I was even scheduled because I just knew I'd need hip surgery. There is an agency here that you can get whatever you need for $1. It was great, I got 2 canes, a walker, a commode, a shower bench, a wheelchair, crutches--everything! Wish you were nearby, so you could use it.
You'll figure it out. Just remember, safety first. Don't do anything that might hurt that nice new hip.
