Help identifying sores on frog's face

[Lunchbox]

Raise your temp up a bit and it looks like your substrate is too wet. Water that pools will become stagnant and bacteria will begin to make the frog sick and potentially cause wounds such as this. Though usually on the frogs stomach and thighs not the face like this.

You say you also feed him crickets. Do not leave them in with the frog for an extended period of time unsupervised. They will bite and attempt to eat the frog.

Any sharp surfaces on the mentioned furnature? Has the frog been shedding normally?

For now address the above issues and you can put a triple antibiotic ointment like Original Neosporine or Polysporine on the wounds daily.

Any additional information about your clean up crew, spot cleaning, ect could help.

I had already preemptively raised the temperature up a bit. Currently resting at 82F. And the substrate looks exceptionally wet in this picture because I had just been spraying him down gently to get a good clean picture of the sores. Usually it's not so damp. I still appreciate the call out though. Especially on the temp I checked it for the initial post and turned up the set temp the next day.

I have been feeding him frozen fish and shrimp and crickets. He's a less aggressive eater than my fantasy frog, but he usually gobbles everything up given enough space and time. My theory is/was cricket bites though. I fed him 6-7 dusted crickets the night before. All the crickets were gone in the morning but I didn't watch him eat them all before going to bed (I usually don't put the lid back on until he's eaten them all. I'm not sure if I should cut crickets out of his diet all together or restrict them to 1-2 at a time as a vitamin vehicle from now on.

There is a rock with a sharp-ish corner on it in the vivarium. Although I'd be surprised if he bashed his face on it. I'm only aware of him changing positions in his tank maybe 6 times in his life.
He seems to shed pretty normally. Maybe a little less frequently than my dumpy frogs or his fantasy frog neighbor.

I've got about a dozen Armadillidium maculatum and about a dozen of some type of Scaber isopod in there with him. There are also some small white unidentifiable insects of some kind in small numbers. I occasionally see one when cleaning.

I took him to the vet twice since posting and there is some kind of bacterial infection at each sore, including 3 new sores that have appeared in the absence of crickets. I was given a topical antibiotic (Ofloxacin?) to dab on each sore twice daily.

I really appreciate your comment/concern <3

Here's a picture of him looking a little more himself
