Iowagirl,
I can't speak to your particular surgery, though I do have a colleague who had the same procedure (no halo though) and is doing quite well now. Of course, her job is a sit down kind, so that helps.
I imagine this is a tough week for you, as the surgery is looming out there. As if you don't have anything else to do...these are a few suggestions. Before my surgery, I went to the store to stock up on bulkier/heavier things (ie, bottled H2O, soda, dog food, TP) as well as frozen/easy to eat things, knowing that it would be hard for me to manage those in the store and getting them from my car to my house while in a cast/NWB. If you haven't gotten your handicapped placard, it's much easier to do it ahead of time. My dr didn't sign the form until the morning of surgery, so I couldn't get mine until the next day, on the way home from the hospital...and I was painful then, but needed it.
Anyway...good luck with everything! Update us with how it all goes...it's a tough surgery, but so worth it (eventually).
