about a week ago i noticed 2 red bumps near my butt (they look like pimples, with no puss or anything, are are painful when they rub against clothing) and today i noticed lots of red bumps but only in ht epubic hair region (i shave so they could be racor burn or ingrown hairs) but the thing that kind of worries me is that I've been having irritation and itching, mild but enough to bother me. I'm supposed to get my period tomorrow and always is kind of itchy before it starts. I haven't been sexually active in over and month. So could this be herpes or just an infection?
