Quick Update
It's day 4 and while the "rash" is still very visible you can finally tell it's fading. I'll keep everybody updated and by the first on the month I'll post a picture of what he looks like now.
While the rash is not attractive to look at his behavior hasn't changed. He still eats, drinks, poos, and gets around OK. The arm most effected by this rash still very much has a grip, and he still would rather spend all day sitting on my head instead of being in his nice warm tank. So all and all I think he is doing good as long has his behavior doesn't change I think I'll keep him away from the scary guy who man handles me ie: the vet lol.
