Well for an update, our snake is doing great!!
As for the sock it is still a great idea that works, however now I don't even bother trying to get his head in it, all I do is lay it over his head and he just lays there while I give him his shot.
He is eating great and his body is filling out. It will be a month or two I think before his body is rounded out again. I have several more injections to give him. His wound looks great. The skin is white with just a scab line down the middle. He is in the process of shedding but again the wound area looks great!! There is no more fluid developing under his skin and he is much more active in his cage now that he is feeling better.
Thanks to everyone for their support and advice.
