Hi. I'm online and happy to answer your question today.
I think you are correct....sleeping with your head low most likely contributed to the swelling. As long as there is no significant pain, discharge or evidence of infection I think you are already doing the right thing -- continue the ice packs and I would expect the swelling to start improving fairly soon.
If things don't seem to be getting better I would contact your transplant surgeon and let her know what is going on and see what she says.
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
