And there isn't any puss whatsoever, which my understanding was often more indicative of an infection.
The fang marks are pretty distinct in this case.
As a general rule, the absence of pus doesn't rule out an infection. Infections (especially of the Staphylococcus aureus variety) are quite often misdiagnosed as being spider bites. But I'd expect that you'd be in a considerable amount of pain with the symptoms spreading beyond the area that they've been localized to by now, rather than experiencing just itching. However, if the redness begins to spread out from beyond that area and the symptoms worsen in any way, you'll really need to get it checked out further ASAP.
