Just to keep in mind a reptile infection is never really going to ooze actually. It will lump up and become more of a bump that will get larger and larger and larger. Reptile puss is very hard, it looks a bit like dried up old cheese that has been sitting on your counter for a week. Most of the time the scales will actually heal back and the infection will abcess inside the body. So at this point for him.i would keep it clean with a bit of betadyne every day. This will prevent infection and clean it out as well. Make sure there's no large gaps or sharp areas and keep an eye out for inflammation.
