We aren't seeing it, so it's impossible to evaluate your snake...other than avoid Neosporin for anything other than limited temporary first aid of minor injuries, as it has
a petroleum jelly base which can cause scale/shedding issues (bad sheds & scales de-laminating). Betadine is safe to use on snakes, but a better antiseptic is Vetericyn-
Petco & some other pet stores carry it, or you can buy from Amazon. It's a water-based topical antiseptic get that's MADE for use on snakes/reptiles.
