Do belly bands really help after a c section? Or what are the best ways to handle the pain , etc?

my hospital gave me a belly wrap 800 MG ibuprofen will b ur best friend for the next few days take it don't skip it I didn't take but 4 at the most Percocet the whole time

I've heard that they help with the healing time and helping get everything back to normal, if that makes sense. stuff about weight loss and snapping back quicker is kinda mixed though.
