I think many of us the first time we get up to walk its hard because
we are stiff. So maybe find some exercises that will relax your
legs and feet before walking.

Then I would keep working the recumbent bike. And if you do
the physical therapy make sure they realize you just want to
work on keeping your back from hurting as much as possible.

Remember you are the boss, and can do as much as you want.
Or in this case the least you want.
