I think you meant "irritated".
But, yes, the vet you spoke to sounds like she knows what she's talking about. Bacteria under the skin can cause raised bumps like yours when the body's defenses try to get rid of the bacteria. Any reptile has a significant amount of bacteria in it's saliva and many many people have reactions to reptile bites. I had a few bumps like that when my BP bit me last year.
Keep the area clean and keep an antibacterial/triple antibiotic ointment on it and it should be fine. Make sure to see a doctor quickly though if red streaks begin to appear. I'm sure you'll be fine, but red streaks can indicate that the infection is entering the blood stream and you may need an antibiotic. If that happens, it would be important for a doctor to look at it right away. BUT I wouldn't worry - that isn't likely to happen, its just something to watch out for.![]()
