I just recently took my ball python Salem to the vet to have his belly checked out for burns. It turned out there was actually a shed coming, and that's why his belly was so pink. But after I took him home from the vet, I noticed he made.. clicking noises. Upon researching these "clicking noises" I read that they tend to click when shedding, but they also tend to click when they have RI, which horrified me. So I checked his mouth for bubbles earlier today, and there was no bubbles. I gave him a vitamin E bath tonight though, and he was clicking again. I was frightened, so I checked his mouth again. This time I found very small bubbles, but there weren't very many of them. I just spent all my cash on taking him to the vet for his pink belly. What other signs should I check for? Should I wait until this shed is over to check again if there are any bubbles? He's not wheezing, he's not sitting with his mouth open, he just.. clicks. Mainly when he's being handled. Sometimes I hear a squeaky snort, I can't tell if its my snakes or my cats, but that's not even once a week and hasn't happened recently. I'd just like to know what I should be watching out for.

He's also been urinating a lot.
