emag, what a lovely first post...reaching out to help reassure another member. Welcome to the forums!
Sassy, I can't really add much to what's already been shared. For the most part, you will probably have very little pain from the surgery, but you will almost definitely have the shoulder pain from the gas used to pump up your abdomen. Peppermint tea and heat will help with that, and Extra Strength Tylenol is likely all you'll need for pain relief.
Good luck with it, I hope it goes well and the doctors find the answers they're looking for.
