If you've had them swabbed, isnt that quite conclusive? Given that you werent taking any antivirals before.
Alot of rashes do involve bumps, including non HSV rashes like jock itch, dermatitis, etc. Im a bit uncertain about my own diagnosis (might begin my own post soon), but I think you ought to be in the clear.
Just note though, and I'm really not trying to fearmonger- but HSV1 can be present on the genitals. It's possible that you contracted it there as opposed to having a new HSV2 infection.
Anyways, keep us updated and wishing you all the best.
