Concerned about IJ

[Void]

My male Dumeril had the same sudden attitude change awhile back. Noticed his tongue wasnt coming out of his mouth and felt a lump on his bottom jaw. Took em to the vet and he had an abscess in his mouth and that was causing him to be mean. Got it cut, drained and with some medication treatments he's back to being friendly.

Not saying thats whats wrong with yours but it could be something inside of him making him like that so Id take em to the vet for a check.
