Water retention?

Hi ladies. Has anyone had problems with water retention post-C section? I am 4 days post op and last night into today I've had crazy swelling. That added onto the fact that according to the scale at my doctor's office, I weigh 9lbs more than I did 1 day post op makes me think that with all the fluids I had pumped into me (I was induced for two days before the surgery itself even happened) that my body is just hanging ounce of fluid. What has helped? I'm trying to drink a ton of water hoping it will help but so far no luck 😔
