A little help please

[n8whitie]

So heres my situation. I just came home today and pulled my red-tail out from hiding under the substrate and his whole head is all swollen.It looks like he just had some major dental work.
he is also acting kinda weird too.I just went back to look at him right now and it has kind of gone down already but his lower mouth is still puffy.
Any takers on this one?
I fed him a small live rat two days ago but he wasnt bit or scratched by it, I watched the whole thing.Im switching to pre-killed anyways.
Please help me on this, I am puzzled as hell.

Thanks , Nate

Are there any visible wounds? What is the condition inside the mouth? By acting weird, what exactly do you mean? Stomatitis can cause the mouth area to swell, but not the entire head. Is there anything that may have been able to injure him in his cage?

Hey, thanks for replying. I havent noticed anything out of the normal.All the swelling is gone now and he is back to normal.
hmmm. Its a mystery to me. If it happens again Im going to take him in.
thanks linds, n8
