Hi Ironwill,
I don't remember exactly when the real swelling goes down, but I always describe log-leg as lasting about a week, so I would guess about a week, so I am hopeful you are almost in the clear. Of course, if you are really concerned, call your surgeon's office.
While you technically just said "getting out of bed", I agree that in and out of bed is the hardest thing post-surgery. What worked for me (and I really only discovered it late in my first recovery) is the inchworm method. It was a huge improvement for me. Basically just worming your way from and to the foot of the bed using your good leg and your arms. When going to lay down, you sit at the foot of the bed, as far back as you can, lay back, and then begin the worming your way back. Getting out do the reverse.
Nothing ever hurt worse than trying to get out the side of a bed, especially without a rail.
Good luck!
Mike
