Random bump appeared 2 days ago

So theres just 1 bump on my right vagina lip and it just came out of no where. What do you guys think it is? i havent seen it before it kind of looks like a pinple to me but this has never happened to me.

These might be better pictures

does it itch or is it painful? filled?

and is that the only one?

it does itch sometimes and it hurts when im walking i think because its rubbing against my underwear and it looks like a pimple ready to pop so it may be filled a little bit and yes this is the only one

i wanna say its a pimple! if it doesnt clear within a week, you should go to the doctor to atleast know what it is, but i think its just a pimple
