i am glad that you went to the doctor for an exam and testing. from what you have described it does not sound like herpes. a primary (new) infection typically takes 2 to 14 days to present itself. a herpes outbreak typically lasts 1-3 weeks and consists of blisters which cause pain itching and burning.
noticed a rash on my butt most receded next day except two now-scabs which have not hurt/itched at all. is this herpes? . the day after a sexual encounter i noticed a rash on my buttocks on the skin surrounding the crack (but not near the anus). however the next day the majority of the rash disappeared except two bumps about half an inch apart for each other. it has been 5 days and the bumps have scabbed over but throughout the process the bumps did not itch burn or cause any noticeable discomfort at all. i am waiting for the blood work to come back but am doing some research in the meantime.
