Yeah, Terry hit that one the head. Its definitely an ulcer, although its hard to say what caused it other then its bacterial (did the infection just appear, was there a scratch where it took hold, did a parasite open the door to infection, etc). The antibiotics are the way to go atm.
Btw, he looks SO pathetic in the net LOL
