Whites Tree Frog Bump on Head

[picklelily]

The bump appeared bruised yesterday and opened up today as a reddish sore. I'm applying polysporin (with no pain killer) twice to three times a day. The red area appears larger at the moment than it did this morning. I'm really worried about her. She is in a quarantine tank and not happy about it. She's eating and I did find some poop.

Oh no, I'm so sorry to see this happen to her. I would really advise a vet visit, even if it's someone with limited amphibian experience. The way this is developing is making me think she either has a parasite or an abscess. Both are bad news and would need vet intervention.
