Yeah, crutches, but dang those things hurt me to try to use them, and didn’t seem like much use. I was probably doing it wrong, somehow. I ended up barely using them, preferring to just lie around, crawl, hop, and/or be dragged around on a blanket by my then girlfriend, for a few days, rather than try to use crutches. After a few days, I could hobble around, not bothering with trying to make crutches useful. I think the whole experience had me unable to really walk for maybe a couple of weeks.
Definitely that and other immobilizing injuries have had me grateful for my health and ability to get around normally, and with a greater realization of how fragile we are, and how intact we need to be to get around well. A badly sprained joint, a back that goes out, even a cut on the knee, can make a person barely able to stand or get around, a challenge to get dressed or stand up or lie down or sleep, etc.
