WTF with red swollen toe

[Nyrasoren]

Hello all!
i received three whites tree frogs in the mail today, and they're in quarantine right now. I was handling one frog to inspect her really quickly after taking her out of her shipping container, and noticed her front right "thumb" is red and swollen. I will attach a photo of her toe in this post. What should I do to help heal her? Any ideas of what might've happened, maybe she pinched it somehow? Her toe is not broken, but is just stuck onto my finger in an odd fashion.

Thank you in advance!!
