Hello! I recently got a Brazilian butt lift by a board certified plastic surgeon. It is day 4 and I am still in a lot of pain. I started off with a bmi of 33.6.The doctor took out a total of 7 liters of fat (6900cc to be exact) from back stomach flanks and inner thighs. He injected 1050 cc into each butt check. I've had to urinate every 45 mins and the pain is unbearable. Is this because 6900 cc is considered large volume lipo? If so what is standard? & is 1050 per cheek good for a big butt?
