I may be able to help, tell me some of the other things its doing besides driping mucus. I would get it checked out if it get's worse and i mean realy bad if you let it go to long it might turn in to paramyxovirus, a virus that can kill w/ in 7 days. Your snake may be slightly uncordanated y it has its minor RI. A tretment for it if it gets bad may be Atropine at .02 to .04 Mg per Kg of your snake, and injected twice a day. not to worry youhope yor snake feels beter!
