Not sure if I should be concerned…

a few days ago i noticed this ulcer on my vulva. in looking at it each day, it is unchanged in size or appearance. it does itch a bit when i touch it and theres a mild sting when i pee, but otherwise its unnoticeable. im thinking its herpes but i have no other symptoms and only the single sore. thoughts?

get it checked out, if youve had a yeast infection could be because of that also

any updates ??

only that I woke up a few days later and it was gone, no scabbing, just disappeared. i have an appt with my obgyn in a couple weeks so im going to ask about it
