Maybe it is just his shed. He is small so it is hard to get his mouth open. I used a sideways toothpick and was able to get a couple quick looks. It all looked pink and I didn't see any kind of fluid. The popping sound is still somewhat (maybe even more) infrequent but he is also still mouth breathing.
I think will probably wait. I hope I'm not making a mistake though. SO frustrating!

Thanks for the advice all.
