I wish i could help you with some advice Walleye---but seeing as I am not allowed to bear weight yet, I don't have much to offer!
Hang in there----I have an appointment Wednesday also, so maybe I will be able to see what advice you get, and help with my own transition to PWB and FWB!!
I hope you don't have an infection, but I had one last year after my surgery, and I know, it is NO fun!! Feel better, and keep doing those little exercises you are doing while sitting----somethings better than nothing!!
Hang tough !!!
