I had this too! I had 4 units transfused during surgery along with a lot of IV fluids. I was on my stomach for at least 8 hrs and when I woke up my eyes were so swollen I couldn't see! I can't even imagine what I looked like. My cheeks and under my chin were swollen too along with arms and partially my legs. They gave me Lasix. I really haven't had a chance to inspect my body yet cuz I'm still in the hospital. Been drinking water like its going out of style. ;-)
