New bump on my Dumpy?

[Nekogekko]

While taking my frog out for a photo shoot, I noticed she had this red bump on the side of her head. It’s firm, looks red like it’s possibly painful or inflamed? She doesn’t seem to mind me pressing on it, but I’m worried it’s an abscess. I don’t let feeders go in the terrarium, but it does look like there’s a small puncture. I’ve only ded super worms recently, but I didn’t think their jaws could do much damage? I have no idea!
I do want to note She was tested positive for parasites last month, but her and my other two frogs have since been treated and are parasite free. Not sure if it could be something related.
Any advice is greatly appreciated!
