My tummy winces in sympathy. I had one of those done many years ago. Are they doing the c-incision or taking things out vaginally?
There is an herb called arnica available in both a tea and a pill that is really helpful with post surgical inflammation. Something I know way more about than I would like to. I am usually the first to call bs on woo-sci herbs but this was actually recommended to me by a surgeon.
Heal well. BTW you have made some great progress on your weight. Well done!
