I have always had a cyst on the edge of my lip near my clitoris. But I have just saw three little pimple look bumps near my cyst. What can this be?

Vesicles? Little pimples, painful with pus, possibly herpes. Get it checked anyway, there are a variety of different causes of genital lesions, some which, if untreated, can ascend into the pelvic region and cause permanent damage, such as sterility.
