Oh you poor thing, I do feel for your situation! I spent 1 1/2 yrs in assorted casts and on crutches after a car accident...it was the pits, but for even short term inconvenience its no fun either! Many good ideas already thrown your way...I would add that with a 2 story house(I lived in an upstairs apt so had a flight of stairs to deal with regularly) to always remember that the bad foot goes down first and when going upstairs always lead with the good foot(kind of the good goes up, bad goes down...heaven/hell theory!). When possible only use one crutch on stairs and use the handrail if one is available...you will keep your balance better!
I got a shower chair and used it in the tub with a handheld shower so I could control where the water went better...plastic wrap and garbage bags were my best friends! Much easier to do the hair washing this way too!
If you're gonna be at this for awhile you might ask your Dr if you can switch over to a walker at home...if so then you can put one of those baskets on the front of it(yes, like the little grannys do at the nursing homes!) and be able to carry things from room to room with you. When it comes to cooking, just don't try and carry hot food in your hand and use crutches at the same time..a recipe for pain if there ever was one!
If I can recall anything else that hasn't been suggested already I'll add it on as it comes to me! Hang in there! Its not fun, but once you figure these things out it becomes much less a dilemna and can even be a great conversation starter(?!) at the markets! I made up great stories after the first year on crutches...the truth got very boring!! (not THAT truth!) Good luck! (((Aude))) bythesea
