My friend got a boa today from a reptile show and when he got him home he noticed there was a bump on the right side of his mouth. I haven't seen it yet, but hes describing it as a pretty big bump on the side of its mouth right under his eye. I'll be over there tomorrow so I can get a picture, but does anyone have any idea of what it could be? The snake will be going to the vet ASAP if it's not an easy fix
