I am not sexually active however I do get cold sores every now and then (not recently) and today i woke up with what I felt was a mosquito bite on my vagina lip. it did not burn but it did in fact itch. this issue has stopped however later in the day i noticed a small welt like bump on my vagina lip and was wondering if anyone knew what it could be? it does not hurt or itch at all however I'm extremely scared of the possibilities of what it could be

could it be an allergic reaction to something?
