Ya might consider using crutches (or maybe just one). They let your armpit(s) help support some of the weight.
Been <somewhat> there with a severe ankle sprain. One crutch worked fine for me.
I asked for crutches and he refused to let me have a pair. I don't remember why now. I wish they would just give me a standing Rx for that Versed stuff. That way I would have an excuse for not remembering anything.
