So I just noticed this on my male cinnamon's face the other night. He has a bit of a bump on the right side of his upper lip.









You can really see the swelling here.






I did some hunting around for similar situations and looks like the largest potential culprit could be an abscess, ick. But I also noticed his nose seems almost wrinkled and dried out, like maybe he has some shed still stuck on there that I didn't notice and it's causing issues? I can't remember the last time he shed but I think it was sometime in december. He's eating fine, chowed down several rats for me recently after being his usual picky self for a while. He wasn't interested in one last night though, even though he had his head poked and was tasting the air and looking around, but he just never struck at the f/t I offered him (rather typical to refuse every so often for him though). There's no weezing or trouble breathing, no listlessness or any other sign of illness, he's solid as a rock and very perky. The flesh doesn't even really look red or nasty around the bump, although I didn't open his mouth to do a full inspection.

Any thoughts? I'm considering giving him a warm tub of water to soak in to see if there is stuck skin on his nose that needs to be loosened up, but if there is I'm not sure how to get it off since that's such a fragile area.
