So pleased you've got a plan. We both seem to have been swinging between the treatment plans for an eternity now!
They started my rad hysto 2 weeks ago but found cancer in my lymph nodes so just removed all of my lymph nodes my fallopian tubes and relocated my ovaries instead. Although healing time they said was the same.
Apparently you can get pain from trapped wind from all the air they pump into you so affter surgery I made sure I drank plenty of water and avoided any foods that would make me feel bloated and took some peppermint teabags with me to have instead of normal tea and I didn't get any wind pain.
I also had to rethink my outfit home as I swelled like a balloon. Haha. I had 3 incisions in my knicker line, 2 in my belly button, and one higher up. So pants/leggings/trousers were a bit tricky. I ended up going home in an old maternity dress. My cheeky husband asked how long I was going to use the excuse of "swelling" for not fitting in my clothes.
Pain wise it's all totally manageable. Just take the pain killers they give you and you'll be absolutely fine. I think I started to feel a bit more human after a couple of nights.
Good luck xx
