Just bringing this back up as a reminder to keep a close eye on your snakes and look them over regularly for problems.
As I took him out of his tub tonight to do the daily cleaning and treatment of the area, I found pus underneath the small scab when I wiped it away as it was loose. Digging deeper, I found even more pus. Right now I'm doing what I can until I can get Boo in to the vet tomorrow. I feel horrible that I didn't notice all this going on sooner.
Please say a prayer for the little guy. And a huge thank you and a hug to Heather for the advice on what to do until I can get him in.
