I didn't read all the posts, but sounds like she should be fine for your clinic. As long as she isn't in pain when she moves and the infection doesn't spread, she'll be fine.
I love Swat and Furazone for healing up cuts. Both keep the flies away and also help help amazingly fast. Both are also relatively cheap at most feed stores. i think I saw a little tub for about $7 last time I looked, and the stuff last forever. I use one or the other for all my pets.
