Wow, that is ugly. It reminds me of the wound I got when Finn pulled me down a couple of stairs and I had to grab a wooden wall slat to avoid falling down. That hurt, and, I know I bumped into things too, ouch. The way I avoided hitting my finger into stuff again was to make the bandage around it really obnoxiously big, probably about an inch of bandage wrapped around my finger. I didn't hit it after that, I was always very aware of it. They have ouchless pads you can put over the wound, too, before you wrap gauze or bandages. I kept pulling stuff out of my wound before I got the hurt free ones. that was awful. Just some suggestions if you wanted to try different bandages. I'm sorry your girl bit you that hard.
