Hello everyone.

Sorry if I'm posting in the wrong section.
My young bumblebee was a bit grumpy yesterday night (just fed him 3 days ago), and he tried to strike at me twice from within the enclosure and he hit the enclosure top (I was just viewing him from outside the enclosure at that time). And he kinda 'yawn' and tried to 're-adjust' his jaw after the second strike, presumably feeling a bit of pain after hitting the plastic top
However, this morning, I noticed that there is some kind of small swelling at his lower mouth area (external, not inside his mouth), presumably an injury from striking the enclosure top.
I never noticed this swelling before and I check on him twice everyday.

Just wondering is it ok for me to apply betadine to the mouth area? What dilution/percentage of betadine should I apply using q-tip? Is it safe for the snake if it accidentally consume some of the betadine used?
First time owning a ball python, so pardon me if this has been asked before.

Thank you!
