The wound is pretty gruesome. It's not like a cut or a surgical incision - it's much bigger and nowhere near as straight. It is, however, much straighter than I ever thought it could be. There's some swelling and separating, which is to be expected. New skin will grow to cover the separation. We're keeping it clean and bandaged. Thankfully, I have a lot of experience with wound care from when the hemangioma was severely ulcerated. Otherwise, we would have had to go into the office every day for dressing change. Our routine until the next visit to Dr. Haynes it to clean it with soap and warm water every day, cover it with Neosporin, and bandage it.
Aerin is not in any pain. It's hard to believe, especially when you look at the wound. She's using the arm normally and she's her usual exuberant self. We did have two incidents when she had just come home - she woke up screaming in pain. We think she probably rolled over on the arm in her sleep. We gave her Motrin and Pedialyte and she was fine within minutes.
I'll write a full account of the surgery in the next week or so. Aerin and I came home from the hospital with colds and we're both just recovering now. Here is a link to a picture of the wound 5 days post-surgery. It is very graphic and icky, so please don't look at it if you have a weak stomach. Seriously. I cannot emphasize enough how gross it is. Okay, here goes: the picture.
