my snakes respitory infection seems to be getting worse, i raised the heat and the humidity, and now its to the point were she has saliva or whatever it is comming out the sides of her mouth....im starting to get worried

i want to take her to the vet but shes also starting her shedding and i don't want to mess with her.....what can i do for her? should just grab her anyway and take her to the vet or what?
