Have you called the vet? They can tell you if that's something you should expect to see, or if it's a sign of a problem. Most vets will tell you that sort of thing over the phone without having to make a visit.
I have tried to get through to my vet but all lines are busy. It's a 24 hour emergency vet so they could be really busy right now. Hopefully my doctor is there. She sometimes doesn't work overnight and she is the only expert on reptiles.
