Yes, you can sit up. Getting from prone to sitting is a challenge by yourself.
Biggest problem for me was, you really want to let your ribcage stitch back together and the least strain you put on it by trying to lift with your elbows will pop it apart again. You can feel it.
I settled in to a reclined sitting position, maybe about 45 degrees, and mostly remained like that. Also makes it a lot easier to get up and walk around when you need to.
Have lots of pillows handy. Have one firm, medium size pillow to hug tightly when you cough. Keeps things from popping apart.
You’ll be flat on your back for a few days. You can’t really move around in bed because you can’t lift yourself with your elbows. You’re not gonna wanna eat much for a while, so there won’t be much to worry about in the poopage department.
Went without a hitch. Very efficient, had the process down pat.
Checked in hospital 0530 Monday, they kicked me out @ 1300 Wed.
First three / four weeks weeks suck. You have to be very careful to let your ribcage knit back together and begin to heal. You cough alot and it’s very uncomfortable. But you get through it.
Not a pleasant experience, but for me, it wasn’t near as bad as I imagined it would be.
Good luck! Let me know if you have any specific questions.
