Post Pregnancy Swelling

Hi Everyone!
Recently had my little boy on (6/12) by emergency C section. I would say the next day I noticed an astonishing amount of swelling in feet and ankles. I thought this was weird because during pregnancy, I only had a few days of swelling. the Drs and nurses both are not concerned and say it will go down. Wondering if anyone has had this happen and any suggestions.  Currently keeping elevated and monitoring salt in take, but the swelling is painful. Please help!
