URGENT: Need Advice About Ball Python Swollen Face

[Homebody]

For the rubbing/pushing cause, I heard him at night trying to get out of his plastic bin enclosure that measures roughly 32x14x14 inches. Also, the plastic from the air holes sticks inward in the enclosure, which he could have injured himself on (I'm currently trying to get them removed). What makes me uncertain about his face being injured is that there is no apparent injury, puss or anything inside his mouth or outside. The only issue is that his face looks grossly distorted, and he refuses to eat.

I vote pushing injury. I kept my adult male bp in a similar enclosure. I moved him to a larger one when he started injuring himself pushing. Likewise, my bp's only injury was swelling.
