Really curious if anyone else has had this... HELP

So about 2 weeks ago i went to a new doctor because i had a weird rash right where my butt cheek crease, a almost perfect circle and the size of a penny, the same day it appeared is the same day i went, which i had been sweating all day (im an HVAC tech) so i was expecting it to be a heat rash... but anyways... she looked at it for 2 seconds and said its herpies....That was it. No info, no questions, no nothing. They drew blood, didnt specify on the test and when they called stating the results it was just "you have herpies." Still nothing other than that... i decided not to take the medicine due to all the side effects, but within a week or 2 it was almost healed and today i was sweating like crazy since here it was 90 degrees, i noticed like 1 or 2 little white heads. with it still being in the not really a scab form but like the area was shrinking to normal skin. Is that normal? Before it heals a couple pop up, in the same exact spot? Or has anyone else expeirenced this? Ive never had this happen. Never had any issues. Didnt have any symptoms, just this small rash.
