Agressive big boa in a bad condition

[KevinK]

He had his first shed here and tip of his poor tail didn't shed as I see a tip missing on his old skin. He doesn't let me touch his tail so im keeping the humidity on the higher end and spray the tail with water. wish to handle him to see his reactions and to stretch him out of the cage,

He has some reddish smudges on his face I noticed later that day and it seems it got worse or im imagening it. Doesn't look normal, right? He eats regullary. Takes him ages but he eats.
I've read neosporin could be used for injures? If yes for this type of thing, it will be a quest to put the cream on his head.
So, sorry for the long post,
is there something I can do?
Hope you guys can see his reddish face on this pic below.

If you're having trouble with him shedding.....get him off of the aspen you're using and onto either a coconut fiber or cypress mulch substrate of some form. If he's shedding in pieces, that's a sign of low humidity and I guarantee aspen is not helping you. Furthermore, aspen molds FAST when exposed to spraying. There are many boa keepers who use aspen, but to maintain proper humidity levels with it for a boa, you either need a PVC/rack enclosure that holds humidity better than a tank.

I agree with Sauzo, I don't think that's an injury of any kind I think it's the natural coloration on his face.
