One of my Libyan Greek tortoise I recently acquired has some swelling on one side of her jaw. The tortoise is overly very health super dense eats great great eyes I haven’t noticed any other issues. It seems like the swelling is due to a internal issue as I don’t see any injuries that could be causing the issue. I did have a Forsten tortoise in the past that had a very similar thing and it didn’t cause any issues. It’s hard to see since it’s still small
