Crazyhedgehog, I actually hope more people will jump in and offer their opinions. The hard lump is a clue that a snake MAY have cryptosporidium, which is generally considered untreatable. I suspect that the bark in the mouth was part of a last-minute seizure, but you'd want to cut them open (wearing latex gloves) to be certain. Cryptosporidium is a horrible bacteria that people can contract.
