What is this bump on my vagina? Recurring bump on the outside of the vagina. It is full of pus and blood but I don't have a clue what it is, please help?

This . This sounds like a vaginal abscess (infection), they tend to recur. If the area in question does not drain on it's own or you get a high fever see your doctor. The area may need to be incised and drained. Good luck.
