Help is this herpes???? Urgent.

HELP

i thought it was just a boil but i had one of these things on the other side of my leg/butt too. This started off as a red bump but chafing from my underwear caused it to open. is it a staph infection or herpes

I dont know too much but this very well could be herpes and herpes can spread to the butt and anus. Its 11 days later any updates?
