Stinging red bump-like spot on my vagina lip, what could it be?

Herpes?: Stinging red bumps are most likely herpes until proven otherwise. Definitely there are other causes, and you should definitely see a doctor or clinic to get this checked out to determine the true cause. Good luck!

Bartholin's. Herpes.: Lots of things this could be, all of which should be evaluated by a gyn. Could be a clogged gland like a bartholin's or a inflamed hair follicle from shaving/waxing or something infectious like herpes. Pain is your body's way of telling you that something is wrong. Please see a doctor soon and avoid intercourse during this time.
