Not to beat you up or anything, but you've had a few of us tell you this isn't something that we consider normal. A few have said that it could be an infection. But at each post, you seem to want to come up with another excuse or explanation. Well, if you posted this message to get our opinions, that's fine, but what do you want us to do? We tell you what we think and you've taken a different opinion each time. If you didn't want us to tell you our opinion, you shouldn't have posted the message.
BTW, an infection will not always indicate by redness or swelling. But it's your snake, you can do what you want. Snakes are very good at hiding a weakness, some won't show any indication, no matter how sick they are.
