can't help much with the pain stuff, but can suggest that a thick strong knotted rope attached to the foot of your bed will help you with getting up.
Keep the elbows tucked in to your sides and pull from down at your groin and it helps you to get up unassisted.
I have read that current view is DO NOT use a rope from suspended above the bed.
make DAMN sure that the rope is well secured.
The rope should be soft yet strong, not a nylon one. If there is a climbing group you know then some abesiling rope that it out of its safety (due to wear) will do the job perfectly. Should be able to get a few meters for next to nothing.
also, since its 8 days left. Do you like Korean food? Do you live anywhere you can get KimChi? If yes then get your hands on some KimChi (just the ordinary variety, not any of the ones with fish or squid in them) and take that into hospital (or have a visitor bring it). This will help you to 'move' properly after surgery. If you don't start the bowels up (as is actually common) they're going to give you things to have that happen.
I have found (from experience) that this happens to me and that KimChi on the side with lunch and dinner helps that. See my post on that here (

also, I found that the nights were cool, but that hospital blankets (and the bedding) made me sweaty. So I got my wife to bring me in a thin micro-fleece blanket (as we use outdoors). Weighs little and really helped me from getting chills and without as much of the sweats.
Take also a tablet or laptop so you can entertain yourself (and us) posting about stuff that happens in there).
Personally I think you're doing really well at the moment!
