Received this snake via FedEx today, and although he is otherwise in good condition, his face is immediately visibly abnormal. The right side is more swollen than the left, but I think both sides have some swelling; it's hard to tell for sure but his labial pits seem more distended and pink to me.

There is also (not visibile in the photoe) some submandibular swelling on the right as well. Pics below show what we saw when we opened his mouth.

Does this look like mouth rot? A tumour? My vets saw him today but they are not really herp folks and weren't sure. I can get him into a herp vet tomorrow.
