The vet thinks they might be water blisters. NOT blister disease, but blisters from being in too high of humidity. He scraped some of the bumps and came up negative for fungus, and he didn't see any signs of bacterial infections. Said he couldn't rule out past parasites but didn't find any current ones hiding under scales, and wants me to bring in a stool sample whenever the snake poos next. (In case of internal parasites, which wouldn't really change how he looks on the outside but a good thing to check for anyway.) He told me to just be careful on husbandry (temps/humidity) and if anything changes (More symptoms, more bumps, etc.) to come back in. If the first shed doesn't help/change things he wants me to bring him back in to be checked out again, but he was thinking that what it looked most like where blisters from humidity. To be safe, obviously I'm still being pretty careful with QT issues since the vet said that testing negative isn't always an indication it doesn't have fungus, just means it didn't turn up on the test.
