Eye problem with new puget? Advice please!

[Charis]

The eye? Or the injection site? I think the eye at the least itches, she rubs it on the walls quite a bit. The shot seems to bug her while it's being given, but then she calms down & seems normal. We try not to touch her at the injection site just after & then I don't handle her at all for at least a few hours. The needle doesn't leave a mark you can see, it's pretty fine, 29 gauge. She doesn't seem to display any of what I'd consider signs that she's in pain, though with a snake that is sometimes hard to tell. The swelling has gone down a lot, the lip just under the eye is still a tiny bit swollen. And I think the eye itself is slightly less swollen too. It is starting to go a kinda drownish color. She did eat one baby guppie yesterday, I'm hoping tomorrow she'll eat several. Here's a few pics from just after she got her 2nd shot.
