Definitely the is fluids they pump during and after recovery. Also, if you are taking Motrin or Advil for pain, ibuprofen helps to retain the excess fluid. My crazy swelling was worst on day 3 pp, but got a little better by day 5 and the completely gone by day 10 when I stopped taking all medication.
I made sure to elevate my feet during resting/feeding periods. Drink plenty of water and ask for a foot massage. I had minimal swelling during pregnancy and looked like I had softballs in my ankles after surgery. It all went away around 8 days pp.
My swelling was terrible during pregnancy and even worse post-C, until about 8 days pp. Now I'm 12 days out and and almost back to normal. Around 4-5 days out I began peeing like crazy, which I was told is normal. Do your best to keep your feet up so that the fluid makes its way back to your bladder.
